Abstract :
This paper considers the optimal multiuser detection problem for the vector Gaussian multiple access channel with multiple inputs and multiple outputs (MIMO). A practical bit-loading and multiuser decision feedback scheme based on generalized decision feedback equalization (GDFE) is proposed. This GDFE-based detection scheme, when used with an optimized transmitter, achieves the extreme points in the multiple access channel capacity region
