Frequency-Domain Block Signal Detection of Multi-Code DS-CDMA Signals
نویسندگان
چکیده
In this paper, we propose a block signal detection scheme, which combines frequency-domain equalization and signal detection scheme developed for the multiple-input multiple-output (MIMO) multiplexing, for the reception of the multi-code direct sequence code division multiple access (DSCDMA) signals. The proposed signal detection scheme is described first. Then, we evaluate, by computer simulation, the achievable bit error rate (BER) performance of multi-code DSCDMA using the proposed frequency-domain block signal detection and discuss the impacts of spreading factor and code multiplexing order on the BER performance.

A Novel Multi-user Detection Approach on Fluctuations of Autocorrelation Estimators in Non-Cooperative Communication
Recently, blind multi-user detection has become an important topic in code division multiple access (CDMA) systems. Direct-Sequence Spread Spectrum (DSSS) signals are well-known due to their low probability of detection, and secure communication. In this article, the problem of blind multi-user detection is studied in variable processing gain direct-sequence code division multiple access (VPG D...
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 کاملBER Performance of MC DS-CDMA with Frequency-domain Equalization
Abstract Multi-carrier direct sequence code division multiple access (MC DS-CDMA) is a combination of time-domain spreading and orthogonal frequency division multiplexing (OFDM), while multi-carrier code division multiple access (MC-CDMA) is a combination of frequency-domain spreading and OFDM. In MC-CDMA, a good bit error rate (BER) performance can be achieved by using frequency-domain equaliz...

Abstract In multiple-input multiple-output (MIMO) multiplexing, a superposition of data blocks transmitted from different transmit antennas using the same carrier frequency is received. In a frequency-selective channel, joint use of frequency-domain equalization (FDE) and signal detection of parallel transmitted signals is essential. Recently, we proposed an iterative frequency-domain interfere...
متن کاملChip-interleaved DS-CDMA with 2-dimensional OVSF spreading code
Multiuser interference (MUI) limits the transmission performance of the DS-CDMA uplink. In this paper, we propose a 2-dimensional (2-D) OVSF spreading and chip-interleaving to transform the multi-user channel into orthogonal single-user channels. Due to MUI cancellation, the chip-interleaved DS-CDMA with 2-D OVSF spreading has ability to increase the link capacity as well as to provide multi-ra...
