Abstract
A technique for processing received signals in multiple-antenna systems. Received signals from the different antennas (102) may be amplified by a Low Noise Amplifier (LNA, 104) and time- multiplexed by a switch (106) to form a single analog signal. The time- multiplexed analog signal is down-converted (108) 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.
