摘要： A technique for low-complexity high-performance coherent demodulation of GFSK signals involves utilizing a novel phase and frequency tracking mechanism coupled with a trellis search technique to track signal memory in the demodulation process. A method according to the technique may include modeling modulation based upon a trellis. The method may further include estimating unknown parameters, selecting a maximum likelihood path through the trellis, and mapping the maximum likelihood path to an output bit sequence. The technique is also applicable to DSPK and other applicable known or convenient protocols.

摘要： A technique weights noise power used in a demodulation/demapping process using on an estimate of interference and its associated power. Using this technique the effect of partial interference can be ameliorated. For example, a value, σ2, can be used to represent the estimated noise and interference power, and σ2 can be used to modify a received signal to ameliorate the effects of noise and interference. σ2 can be adjusted in response to partial interference, and can be represented by the formula: σ2=σN2+q σI2, where σN2 is “noise power,” σI2 is “interference power,” and q is an interference correction factor.

摘要： A technique for processing received signals in multiple-antenna systems. Received signals from the different antennas may be amplified by a Low Noise Amplifier (LNA) and time-multiplexed by a switch to form a single analog signal. The time-multiplexed analog signal is down-converted and processed using a single RF chain for each signal component. This may result in an N-fold decrease in hardware in multiple antenna receiver systems.

摘要： This specification describes, in part, a technique for dynamic assignment of multiple antennas to different radio subsystems in a wireless device. The technique may include using an adaptive algorithm to allocate antennas to different radio subsystems as a function of, for example, application requirements, power requirements, and/or channel/network conditions. The specification also describes, in part, a technique for adaptively optimizing the use of the assigned antennas and other transmission parameters for each radio subsystem.
