Abstract

Cooperative communications among users in multiple access wireless environments is an efficient way to obtain the pwerful benefits of multi-antenna systems without the demand for physical arrays. This paper poposes a sulution to optimize the weights of partnering users' signals for the minimum error probability at the output of maximum likelihood(ML) detector under the transmit poser constraints by taking advantege of channnel state information(CSI) feedback from the receiver to the tranmitter. Simulation programs are also established to evaluate the performance of the system under flat rayleigh fading channel plus AWGN(Additive White Gaussian Noise).,
