Removal of Multiple Access Interference in DS-CDMA System
Multiple access interference (MAI) is a factor which limits the capacity and performance of DS-CDMA systems. MAI refers to the interference between direct-sequence users. This interference is the result of the random time offsets between signals, which make it impossible to design the code waveforms to be completely orthogonal. While the MAI caused by any one user is generally small, as the num...
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 کاملParallel multiple access interference cancellation in optical DS-CDMA systems
This paper investigates the Parallel Interference Cancellation technique in Direct Sequence Optical Code Division Multiple Access (DS-OCDMA) system. In the proposed system, the estimated interference is removed from the received signal. We have developped a new approach to obtain the analytical expression of error probability in chip synchronous case, for Optical Orthogonal Codes (OOC). We have...
متن کاملUsing Chaotic Sequence in Direct Sequence Spread Spectrum Based on Code Division Multiple Access (ds-cdma)
The paper aim was an investigation on use of chaotic sequence in DS-CDMA. The DS-CDMA systems offer physical layer security without the need for a significant increase in computation or power requirements. Nowadays, DSCDMA has been used widely. These systems suffers from multiple access interference because of other users transmitting in the cell, channel inter symbol interference and additive ...
متن کاملOn Multiple Access Interference in a DS/FFH Spread Spectrum Communication system
This paper describes the influence of Multiple Access (MA) interference on the performance of a non-cohcrcnt hybrid Direct Sequence Fast Frequency Hopping SSMA Communication system applying FSK-modulation. The MA-interference plays an important role in determining the total interference in a Spread Spectrum system, especially in a non-cellularenvironment, where Power Control is hardly possiblc....
