Joint equalization, soft-demapping and phase error correction in wireless system with receive diversity

Wireless communication technology enables equalization, this soft mapping 86 and the phase error estimate (74) functions may be performed in combination on the basis of the observations of multiple transmitted symbols in a wireless communication system using receive diversity. Multiple observations of the symbol is obtained from the multiple antenna paths in the radio receiver. Equalizer, and the soft reverse mapping 86 and the phase error estimate (74) functionality may be integrated into a shared instead of being distributed among separate hardware block diagram of the hardware, thus promoting the reduction in size, complexity and cost in the radio receiver thereby.
