Abstract
A method and apparatus for estimating a transmitted symbol from a received sample as a function of Signal-to-Interference and Noise Ratio (SINR) of the received sample. The received sample is quantized and mapped to a region of a grid overlaid on the transmitted symbol constellation. The region may correspond to a symbol estimate value or may be processed further to obtain a symbol estimate value. The regions in one embodiment are rectangular. The symbol estimate values may be stored in a memory storage unit.
