Synchronous Mc - Cdma in Dispersive , Mobile Rayleigh Channels
نویسنده
چکیده
Time variations of the mobile radio channel cause InterCarrier Interference (ICI) to Orthogonal Frequency Division Multiplexing (OFDM) and Multi-Carrier CDMA (MCCDMA) radio links. This paper evaluates the effect of Doppler and delay spreads on the performance of an MC-CDMA receiver. An MMSE receiver is analyzed for MC-CDMA transmission over a mobile channel with Doppler. A simplified, pseudo MMSE receiver is proposed that does not need to perform real-time inversion of a large matrix. It performance is shown to be better than for (uncoded) OFDM.

Bit Error Performance for Asynchronous Ds Cdma Systems Over Multipath Rayleigh Fading Channels (RESEARCH NOTE)
In recent years, there has been considerable interest in the use of CDMA in mobile communications. Bit error rate is one of the most important parameters in the evaluation of CDMA systems. In this paper, we develop a technique to find an accurate approximation to the probability of bit error for asynchronous direct–sequence code division multiple–access (DS/CDMA) systems by modeling the multipl...
متن کاملPerformance of Frequency-Time MMSE Equalizer for MC-CDMA over Multipath Fading Channel
A cyclic prefix of sufficient length is inserted (longer than the maximum delay spread of the channel) in Multi-Carrier CDMA (MC-CDMA) transmission over dispersive channels such that the channel, as seen by subcarrier, is a simple multiplicative distortion in the frequency domain, that can be compensated for by a one-tap Frequency Equalizer (FE). If, in addition to the spectral inefficiency cau...
متن کاملEffects of multipath propagation delay on uplink performance of synchronous DS-CDMA systems communicating in dispersive rayleigh fading channels - Electronics Letters
The effect of the maximum asynchronous arrival time difference (AATD) of the delayed multipath components on the uplink performance of synchronous DS-CDMA systems is investigated, when communicating in a frequency-selective Rayleigh fading channel. Numerical results demonstrate that the achievable user capacity gain may be as high as 64% at a bit error rate of 10 , when the maximum AATD is suff...
متن کاملThroughput Improvement of STS-Based MC DS-CDMA System with Variable Spreading Factor
The throughput enhancement of Space-Time Spreading (STS)-based Multicarrier Direct Sequence Code Division Multiple Access (MC DS-CDMA) system is investigated in this paper. Variable Spreading Factor (VSF) is utilized to improve the data throughput of the system. In this contribution, an analytical approach is proposed to compute a new expression for the Bit Error Rate (BER) performance of t...
متن کاملJoint estimation of correlated multi-carrier DS-CDMA mobile fading channels based on optimal filters
Abstract: This paper deals with the joint estimation of rapidly time-varying and correlated Rayleigh fading channels in synchronous multi-carrier direct-sequence code-division-multiple-access (MC-DS-CDMA) systems. Usually, when the multiple carrier fading channels are modelled by autoregressive (AR) processes, they can be estimated separately by means of an optimal Kalman filter. However, a los...
