Multiuser Detection for Vector Multiple Access Channels Using Generalized Decision Feedback Equalization
نویسندگان
چکیده
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.

Decision Feedback Sequence Estimation For Unwhitened ISI Channels With Applications To Multiuser Det - Selected Areas in Communications, IEEE Journal on
Decision feedback sequence estimation (DFSE), which is a reduced-complexity alternative to maximum likelihood sequence estimation (MLSE), can be used effectively for equalization of intersymbol interference (ISI) as well as for multiuser detection. The algorithm performs very well for whitened (minimum-phase) channels. For nonminimumphase channels, however, the algorithm is not very effective. ...

Two promising classes of techniques are developed for e cient multiuser detection in codedivision multiple-access (CDMA) communication systems subject to fading due to time-varying multipath propagation. Both are designed to jointly suppress both intersymbol and multipleaccess interference inherent in such systems, and exploit all available time and frequency diversity. The rst is a family of l...

Communications in dispersive direct-sequence code-division multiple-access channels suffer from intersymbol and multiple-access interference, which can significantly impair performance. Joint maximum a posteriori probability equalization and multiuser detection with error control decoding can be used to mitigate this interference and to achieve the optimal bit error rate. Unfortunately, such op...
متن کاملA New Class of Efficient Block-Iterative Interference Cancellation Techniques for Digital Communication Receivers
A new and efficient class of nonlinear receivers is introduced for digital communication systems. These “iterated-decision” receivers use optimized multipass algorithms to successively cancel interference from a block of received data and generate symbol decisions whose reliability increases monotonically with each iteration. Two variants of such receivers are discussed: the iterated-decision e...
