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

Y Kim, FR Rad, BJ Brickner, J Moon - US Patent 7,173,990, 2007 - Google Patents
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 …
