Pre-equalization Techniques for Downlink and Uplink TDD MC-CDMA Systems
نویسندگان
چکیده
Time division duplex (TDD) multi carrier-code division multiple access (MC-CDMA) systems have recently been proposed as potential candidates for next generation (4G) technology. In order to mitigate multiple access interference, in this paper we investigate pre-equalization schemes for both downlink and uplink transmissions, the former also in a multiple transmit antenna scenario. In particular, new pre-equalizer techniques are introduced and complexity issues addressed. Numerical results are given to highlight the effectiveness of the proposed schemes with respect to other existing pre-equalizer solutions.

On the Performance of Different Channel Pre-Compensation Techniques for Uplink Time Division Duplex MC-CDMA
Time division duplex multi-carrier code-division multiple-access (TDD/MC-CDMA) operates on the premise that there is a strong correlation between upand downlink channel conditions. When using TDD mode, the effects of the channel on the uplink signal can be pre-compensated at the mobile station, based on the channel estimation from the downlink frame. The aim of this paper is to carry out a perf...
متن کاملPre-Compensation of Fading Channels for Uplink Time Division Duplex MC-CDMA Systems
Time division duplex multi-carrier code-division multiple-access (TDD/MC-CDMA) exploits the strong correlation between upand downlink channel conditions of the slowly timevarying channels. The TDD mode enables pre-compensation of the channel influence on the uplink signal already at the mobile station based on the channel estimation from the downlink signal. The aim of this paper is to carry ou...
متن کاملTime Division Duplex MC-CDMA for Next Generation Mobile Radio Systems
Over the past several years there has been increased interest in wireless mobile communication systems that use code division multiple access (CDMA). The systems such us IS-95 (Direct Sequence CDMA, DS-CDMA) and UMTS (Wideband CDMA, W-CDMA) already use CDMA based techniques. On the other hand, thanks to excellent multi carrier (MC) modulation properties in the frequency selective fading radio c...
متن کاملFrequency-Domain Pre-Equalization for MC-CDMA/TDD Uplink and Its Bit Error Rate Analysis
In multi-carrier code division multiple access (MCCDMA) uplink (mobile-to-base station), since different users’ signals go through different frequency-selective fading channels, large multi-access interference (MAI) is produced. The use of frequency-domain equalization reception can only partially restore the orthogonality among different users’ signals, resulting in a severe degradation in the...
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...
