Title:
TRANSMITTER, RECEIVER AND CORRESPONDING METHOD
Document Type and Number:
WIPO Patent Application WO/2007/071106
Kind Code:
A1
Abstract:
A transmitter and receiver in a multi-user multiple input/multiple output communication
system and corresponding transmission method and reception method in which:
upon transmitting, an user information bit stream is mapped to be a symbol sequence
via a symbol mapper mapped symbol sequence is divided into multi-channel data
by a demultiplexer the symbol sequence of each path is appended a cyclic prefix
via a cyclic prefix generator the symbol sequence which is appended a cyclic prefix
passes through a multiplier and said symbol sequence is multiplied by a chip
generated in spread spectrum code generator, and obtains a data frame. Upon receiving
all kinds of interferences caused by frequency selective fading are confronted
by using single carrier frequency domain equalizer the influence of error propagation
due to serial interference elimination is reduced by using iterative layered
space-frequency detection algorithm. Present invention restrains effectively
ISI and ICI between multi-user signals thus improves average performance of
the system, and increases greatly system capacity.
