Delay-Induced Scattering With Phase Randomization And Partitioned Frequency Hopping
view source -
US Patent:7336694, Feb 26, 2008
-
Filed:Oct 10, 2003
-
Appl. No.:10/683891
-
Inventors:Arunabha Ghosh - Austin TX, US
-
Assignee:SBC Knowledge Ventures, L.P. - Reno NV
-
International Classification:H04B 1/00
-
US Classification:375130, 375132, 375138
-
Abstract:A first copy and a second copy of a signal, which comprises a plurality of TDMA frames, are transmitted from the same antenna. Relative to the first copy, the second copy of the signal has a fixed delay and a random phase. The random phase changes from one of the TDMA frames to another of the TDMA frames. A group of hopping carrier frequencies are partitioned into at least two sets of carrier frequencies. The first copy and the second copy of the signal are transmitted using a sequence of the hopping carrier frequencies, wherein consecutive pairs of the hopping carrier frequencies for consecutive pairs of the TDMA frames are not from the same one of the at least two sets.

US Classification:375341, 714795
-
Abstract:First and second partially collapsed metric values are determined for each bit in a symbol transition. Each first partially collapsed metric value is a cumulative metric of starting in a first state and ending in a second state in L transitions with the respective bit in the symbol transition being a first value. Each second partially collapsed metric value is a cumulative metric of starting in the first state and ending in the second state in L transitions with the respective bit in the symbol transition being a second value, the second value differing from the first value. For each bit in the symbol transition, a relative likelihood value is determined based on its respective first and second partially collapsed metric values. A symbol is decoded based on a hard decision performed using the relative likelihood value for each bit in the symbol transition.

US Patent:7551547, Jun 23, 2009
-
Filed:Jan 28, 2005

International Classification:H04J 11/00
-
US Classification:370208, 375346
-
Abstract:A transmitted symbol matrix and a received symbol vector are transformed based on a non-identity transformation. The non-identity transformation is based on a finite spread of a channel impulse response in a time domain and is usable to improve accuracy of channel estimation in a frequency domain. A transformed channel vector is determined based on the transformed transmitted symbol matrix and the transformed received symbol vector using a channel estimation method. One or more elements in the transformed channel vector are suppressed to at or about zero. The suppressed, transformed channel vector is inverse transformed into an estimated channel vector based on the non-identity transformation.

International Classification:H04B 1/00
-
US Classification:375147, 375141
-
Abstract:A modified adaptive minimum mean square error (MMSE) receiver detects a spread spectrum signal, minimizing interference among multiple users. The receiver receives multiple pilot bits and corresponding data bits. A channel is estimated using at least one of the received pilot bits and, simultaneously, the data bits are detected based on the pilot bit and an inverse of a gain of the receiver. The spectrum signal may be spread in accordance with a wideband code division multiple access (W-CDMA) format, in which the pilot bits are modified to include a predetermined bit sequence of alternating ones and negative ones.

Abstract:A method is disclosed that includes channel estimation for a multi-carrier modulation of a plurality of subcarriers. The method includes performing a first channel estimation to obtain a first estimate of a channel based on a received signal. The method further includes suppressing a portion of elements of the first estimate of the channel to obtain a suppressed estimate of the channel. The method also includes multiplying the suppressed estimate of the channel by a first matrix to obtain a delay restricted estimate of the channel.
