Appl. No.:

10/101903

Inventors:

Danny Thomas Pinckley - Arlington TX, US

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04L 25/03

US Classification:

375296

Abstract:

An apparatus for processing base band signals and method thereof to provide low level signals for amplification that will improve performance of a multi-channel transmitter. The apparatus includes a first Transform Matrix (TM) coupled to one or more input signals; a processing unit coupled to the output signals for modifying according to a predetermined algorithm each of the output signals to provide modified output signals; a second TM coupled to the modified output signals for decomposing the modified signals, each of the output base band signals corresponding to one of the input signals; and a compensation function arranged and inter-coupled to either the modified output signals or the output base band signals. The transmitter further converts the output base band signals to radio frequency signals. A sampler couples either the amplifier input signal or output signal back to the compensation function as a feedback signal.

International Classification:

H03F 1/26

US Classification:

330149, 330136

Abstract:

The present invention discloses a system and a method for memory-based predistortion to reduce the distortion effects introduced by a power amplifier. The distortion effects include both memoryless and memory effects. The input and the corresponding output values of the power amplifier are measured to determine models used for predistortion. Using these models, first, an amplitude memory signal representing the amplitude memory effects of the power amplifier is obtained. Then, the amplitude memory signal is subtracted from the input signal. On the resulting signal, memoryless amplitude predistortion and memory-based phase predistortion are performed to get a predistorted signal. Further, an inverse model of the linear response of the power amplifier is implemented on the predistorted signal. Finally, the output of the inverse model is amplified by the power amplifier to obtain an output signal having reduced memoryless and memory-based effects.

International Classification:

H04K 1/02

US Classification:

375297, 4551143

Abstract:

A postdistortion amplifier that produces a postdistortion amplifier output signal based on a signal input to the postdistortion amplifier reduces distortion in the postdistortion amplifier output signal by digitally predistorting an error signal. The postdistortion amplifier includes a digital predistortion unit that receives a digital error signal and produces a digital predistorted error signal based on the received digital error signal and by reference to a predistorted error signal model.

International Classification:

G08C 25/02

US Classification:

714748, 714752

Abstract:

A technique for transmitting data in a communication network employing Hybrid Automatic Repeat Request includes a first step of grouping data to be transported into a first and second groups in accordance to a decision parameter, such as data size. A next step concatenates data from the first group and encodes into a multi-user packet. A next step encodes the data into a plurality of data packets. A next step assigns available traffic resources to encoded packets. A next step transmits the encoded packets. A next step reassigns a portion of said traffic resources for which a positive acknowledgement has been determined to uninitiated packets or to assist with one or more ongoing transmissions.

International Classification:

H04W 72/00

US Classification:

455450, 4554521

Abstract:

A method and apparatus for establishing an active set of carriers from a plurality of available carriers for a wireless receiver. The active set of carriers can be determined from the plurality of available carriers for the wireless receiver. An indication of which carriers are in the active set can be sent to the wireless receiver, such as a receiver in a mobile communication device. The receiver or mobile communication device can monitor only those carriers that are listed in the active set of carriers.

Abstract:

A communication system distributes, in the time domain, acknowledgment transmissions by a group of access terminals sharing a same time domain resource. A position of one or more access terminals in the group of access terminals is determined and each of the one or more access terminals then sends an acknowledgment transmission, such as an acknowledgment or negative acknowledgement, in a time slot that is N time slots after the shared time domain resource, where N is a function of the position of the access terminal in the group of access terminals.
