Reception of signals in a high rate transmission diversity system

摘要

The performance and symbol rate in a wireless mobile system are increased by forming a transmission code matrix using transformed orthogonal codes, in such a way that the code is robust to channel statistics and operates well in both Ricean and (correlated) Rayleigh channels. Furthermore, the invention enables high symbol rate transmission using multiple transmit antennas, and one or multiple receive antennas, and obtains simultaneously high diversity order and high symbol or data rate.
