Appl. No.:

09/832067

Robert Gold - Los Angeles CA, US

Assignee:

Robert Gold Communication Systems, Inc. - Los Angeles CA

International Classification:

H04B 1/69
H04B 1/707

H04B 1/00

US Classification:

375130, 375132, 375133, 375134, 375136, 375137, 375140, 375141, 375145

Abstract:

A system and method for synchronizing and selectively addressing multiple receivers in a wireless communication system includes a spread spectrum transmitter and one or more spread spectrum receivers. The transmitter transmits a signal having an observable parameter which is pseudo-randomly varied. The receiver measures the relative times between recurrences of a selected value of the observable parameter being pseudo-randomly varied, and determines an initial state of the transmitter based upon the measured relative times. The receiver then synchronizes itself to the estimated current state of the transmitter using the determined initial state as a starting reference. In a frequency hopping embodiment, the spread spectrum transmitter comprises a feedback shift register, and transmits a sequence of pseudo-randomly hopped frequencies determined by the shift register. A receiver is tuned to one of the hopping frequencies, measures the relative times of arrival between consecutive transmissions, and determines the initial code word in the transmitter feedback shift register from the measured relative times of arrival by constructing and solving a set of linear equations. The receiver then matches comprises its feedback shift register to the initial code word, adjusted by an amount of time elapsed during the synchronization process.

International Classification:

H04B 1707

US Classification:

375206

Abstract:

A spread spectrum transmitter for generating a plurality of spread spectrum codes comprises a shift register having a plurality of stages, with a plurality of tap sets connected to selected ones of said stages. Each tap set defines a different spread spectrum code, which may be maximal or non-maximal. Outputs from the tap sets are combined using exclusive-OR gates and fed back to through a table of logic gates to the input of the shift register. A serial data register is loaded from a data stream and clocked periodically into a parallel data register. The parallel data register corresponds to a data symbol and is connected to the table, whereby one of the spread spectrum codes at a time is selected. A code portion of the spread spectrum code up to a designated length is generated for each data symbol. More than one code portion may be simultaneously sent using offset quadrature phase shift keying.

International Classification:

A61F 1300

US Classification:

128165

Abstract:

The invention is a compression device for tennis elbow which compresses the common extensor muscle group of an individual so that he may continue to play tennis despite the presence of tennis elbow. The compression device includes an elastic member which is formed out of an elastic material and which has a tubular shape adapted to provide a compressive force on the common extensor muscle group of the individual. The elastic member has an outer surface and an inner surface. The elastic member also has a longitudinal slit which is fastened together by velcro fastening material. The compression device also includes a non-compressible member which is formed out of a non-rigid material and which is disposed on the inner surface of the elastic member. The non-compressible member is adapted to cover the common extensor muscle group. The compression device further includes a non-compressible pad which is formed out of a non-rigid material and which is disposed on the inner surface of the elastic member so that it covers the attachment area of the common extensor muscle group.

International Classification:

US Classification:

375206

Abstract:

A system for despreading and/or demodulating spread spectrum codes is provided. A data signal is encoded using an M-ary transmission technique, wherein predefined symbol codes are associated with a particular series of data bits. A receiver comprises a plurality of delay elements or a shift register with a plurality of taps configured to recognize one or more the predetermined symbol codes. Delayed representations of the received signal are generated and combined to produce a known output sequence, such as a string of consecutive one or consecutive zeroes, when a recognizable spread spectrum code is received. The receiver shift register may be preloaded such that recognition may occur starting with the first received chip. More than one set of taps may be coupled to the same shift register, so that more than one of the M spreading codes may be recognized by the same shift register. A received set of chips may be identified with a code sequence that has a minimal cross-correlation distance or Hamming distance, whereby a received code sequence with imperfect correlation may be recognized as corresponding to a defined symbol.

Abstract:

A method for communicating using a plurality of spread spectrum codes. A plurality of spreading codes are generated by use of one or more linear feedback shift registers configured with feedback taps. The spreading codes may be maximal or non-maximal. A plurality of code portions are selected, one from each of the spreading codes. The code portions each have the same length and are selected for low cross-correlation and favorable auto-correlation and spectral properties. Each of the code portions is associated with a data symbol representing a unique group of data bits. An input data stream is divided into groups of data bits and, in response thereto, the code portion associated with each group of data bits is transmitted. At the receiver, the transmitted signal is captured in one or more receive shift registers. The receive shift register or registers have tap locations matching the tap locations of the transmitter, and simultaneously detect for each code portion by combining the incoming signal with each of the taps for a given code portion.
