Effect of Interleaved FEC Code on Wavelet Based MC-CDMA System with Alamouti STBC in Different Modulation Schemes
In this paper, the impact of Forward Error Correction (FEC) code namely Trellis code with interleaver on the performance of wavelet based MC-CDMA wireless communication system with the implementation of Alamouti antenna diversity scheme has been investigated in terms of Bit Error Rate (BER) as a function of Signal-to-Noise Ratio (SNR) per bit. Simulation of the system under proposed study has b...
متن کاملImpact of Different Spreading Codes Using FEC on DWT Based MC-CDMA System
The effect of different spreading codes in DWT based MC-CDMA wireless communication system is investigated. In this paper, we present the Bit Error Rate (BER) performance of different spreading codes (Walsh-Hadamard code, Orthogonal gold code and Golay complementary sequences) using Forward Error Correction (FEC) of the proposed system. The data is analyzed and is compared among different sprea...

The impact of using wavelet based technique on the performance of a MC-CDMA wireless communication system has been investigated. The system under proposed study incorporates Walsh Hadamard codes to discriminate the message signal for individual user. A computer program written in Mathlab source code is developed and this simulation study is made with implementation of various antenna diversity ...
متن کاملPerformance analysis of low complexity multiuser STBC MC-CDMA system
In this paper, a low complexity and efficient multi-user Space Time Block Code Multi-Carrier Code Division Multiple Access (STBC MC-CDMA) for downlink wireless communication system is proposed. STBC MC-CDMA provides diversity gain to improve transmission efficiency of mobile wireless systems where both STBC encoder and decoder are in time domain thus reducing the complexity at the receiver side...
متن کاملComparison of BER for BPSK & QAM modulation with Alamouti STBC
On comparing the error performance of various space-time block codes(STBC) for the quasi-static Rayleigh fading channels and with different modulation techniques as BPSK,QAM, it is observed that the slope of BER is steepening as Eb/N0 is increased. It is also observed that a higherorder diversity is obtained with a larger number of transmit antennas, that is, steepening the slope of BER curves ...
