Nonlinear Multiuser Transmission using Multiple Antennas for TDD-CDMA
نویسندگان
چکیده
Multiuser Transmission (MUT), the counterpart of Multiuser Detection(MUD) in the transmitter, can substantially enhance the performance of the CDMA downlink in frequencyselective channels. Besides linear Multiuser Transmission, known as Joint Transmission and Transmit Wiener filters, recently nonlinear MUT was proposed. The contribution of this paper is the extension of nonlinear Minimum BER Transmission to multiple transmit and receive antennas. Furthermore linear and nonlinear multiple antennae MUT schemes are compared for the application of PreRAKE, RAKE and Eigenprecoder. The simulation environment is similar to 3GPP TDD CDMA or the Chinese TD-SCDMA.

متن کاملNonlinear Multiuser Receiver for Optimized Chaos-Based DS-CDMA Systems
Chaos based communications have drawn increasing attention over the past years. Chaotic signals are derived from non-linear dynamic systems. They are aperiodic, broadband and deterministic signals that appear random in the time domain. Because of these properties, chaotic signals have been proposed to generate spreading sequences for wide-band secure communication recently. Like conventional DS...
متن کاملA simple Bayesian multistage interference canceller for multiuser detection in TDD-CDMA receivers
A simple multiuser detector (MUD) is proposed for channels affected by severe multipath and is then suitable for timedivision duplexing code-division multiple-access (TDD-CDMA) receivers. For each user, after coherent combining and despreading, a suitable “Bayesan” memoryless nonlinearity gives symbol-bysymbol the expected values of the transmitted data. These are employed for soft removal of i...
متن کاملBlind Adaptive Space-Time Receiving and Transmitting Diversities For Multiuser DS-CDMA Systems
Blind adaptive space-time processing techniques are developed for both uplink reception and downlink transmission in multiuser TDD DS-CDMA systems to overcome multipath fading effect and multiple access interference. The system consists of a spacetime array, a decorrelator, and a weight-adapter. For uplink reception, a hybrid combination of constant modulus algorithm and decisiondirected algori...

The downlink minimum bit error rate (MBER) transmit beamforming is directly designed based on the uplink MBER receive beamforming solution for time division duplex (TDD) space-division multiple-access (SDMA) induced multiple-input multiple-output (MIMO) systems, where the base station (BS) is equipped with multiple antennas to support multiple single-antenna mobile terminals (MTs). It is shown ...
