Frequency-domain Differential Det for DS-CDMA Mobi
نویسنده
چکیده
In this paper, we show that differential detection of DS-CDMA signals transmitted over a severe frequency-selective fading channel is possible. Joint frequency-domain differential detection and equalization (FDDDE) based on the minimum mean square error (MMSE) criterion is proposed. A simple decision feedback filter is used to provide a reliable reference signal for MMSE-FDDDE. It is confirmed by computer simulation that MMSE-FDDDE provides good BER performance close to coherent MMSE-FDE and shows high robustness against the Doppler spread.

Differential Space-Time Block Code Modulation for DS-CDMA Systems
A differential space-time block code (DSTBC) modulation scheme is used to improve the performance of DS-CDMA systems in fast time-dispersive fading channels. The resulting scheme is referred to as the differential space-time block code modulation for DS-CDMA (DSTBC-CDMA) systems. The new modulation and demodulation schemes are especially studied for the down-link transmission of DS-CDMA systems...
متن کاملFrequency-domain differential detection and equalisation of differentially encoded DS-CDMA signals
Coherent frequency-domain equalisation (FDE) of DS-CDMA signals suffers from channel estimation error. Frequency-domain differential detection and equalisation (FDDDE) for the reception of differentially encoded DS-CDMA signals transmitted over a frequency-selective fading channel is proposed. At a transmitter, the differentially encoded data symbol is spread and transmitted. At a receiver, dif...
متن کاملA Closed-form BER Expression for Differentially Modulated DS-CDMA Signals with Frequency-domain Differential Detection and Equalization
Abstract Recently, we have proposed frequency-domain differential detection and equalization (FDDDE) for the reception of differentially encoded DS-CDMA signals in a timeand frequency-selective fading channel. It was shown by computer simulation that FDDDE using an IIR filter with decision feedback can provide better BER performance than coherent frequency-domain equalization (FDE) with pilot-a...
متن کاملFrequency-domain Differential Detection and Equalization for 2-dimensional spread/chip-interleaved DS-CDMA
Abstract The multiple-access interference (MAI) limits the performance of the DS-CDMA uplink transmission. 2D OVSF spread/chip-interleaved DS-CDMA is an MAI-free system, and hence single-user coherent frequency-domain equalization (FDE) can be used instead of complicated multiuser detection (MUD). However, coherent FDE needs channel estimation. Pilot-assisted channel estimation is not reliable ...
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...
