ABSTRACT:
The method and system for channel estimation in a single channel (SC) single-input multiple-output (SIMO) system described herein may provide a fast and cost effective approach to concurrently determine propagation channel estimates in a single-transmit (1-Tx) and multiple-receive (M-Rx) antennas wireless communication system. A single weight baseband generator may comprise a set generator, a channel estimator, and an algorithm generator. The set generator may generate orthogonal function sequences that may be applied to the M receive antennas and may be utilized by the channel estimator to generate channels estimates. The orthogonal function sequences may be transferred to the channel estimator after a delay. The algorithm generator may generate phase values based on the channels estimates that may be applied to the M receive antennas to improve the system's signal-to-noise performance.
