Abstract
A wireless communication technique enables equalization, soft demapping and phase error estimation functions to be performed jointly based on multiple observations of a transmitted symbol in wireless communication systems employing receive diversity. Multiple observations of a symbol are obtained from multiple antenna paths in a wireless receiver. Equalization, soft demapping and phase error estimation functions can be integrated within shared hardware, rather than distributed among separate hardware blocks, promoting reduced size, complexity and cost in a wireless receiver.
