Abstract

Here, we present an approach to investigate perfect/imperfect channel detection in the maximal ratio receiver combined scheme (MRRC) and a simple transmit diversity scheme (STD). In order to effectively make use of the transmit diversity techniques, the same approach is extended to process the situation of one transmit antenna and N receive antennas in the MRRC scheme (1 times N MRRC) and two transmit antennas and N receive antennas in the STD scheme (2 times N STD), in which the effects of perfect/imperfect channel detection and the diversity reception with independent Rayleigh-fading signals are evaluated and compared
