Performance Analysis of a Concatenated Ldpc Coded Alamouti-based Stbc-ofdm System on Text Message Transmission
This paper investigates the impact of concatenation of an interleaved low density parity check (LDPC) code with convolutional channel coding on the performance of the space time block coded (STBC) orthogonal frequency-division multiplexing (OFDM) wireless communication system on text message transmission. The concatenated channel encoded OFDM system deploys various digital modulations (BPSK, QP...
متن کاملAlamouti STBC MIMO OFDM System using ZCT Precoded Based SLM Technique for PAPR Reduction
OFDM system is combined with multipleinput multiple-output (MIMO) in order to increase the system capacity and diversity gain. However, one of the major drawback of MIMO-OFDM have high peak-toaverage power ratio (PAPR) in order to the signals transmittted on different antennas. In this paper, we propose Zadoff-Chu matrix Transform (ZCT) precoding based Selected Mapping (SLM) technique to reduce...
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 ...

متن کاملAlamouti-Based Space-Frequency Coding for OFDM
We investigate space-frequency block coding for OFDM systems with multiple transmit antennas, where coding is applied in the frequency domain (OFDM carriers) rather than in the time domain (OFDM symbols). In particular we consider Alamouti’s code, which was shown to be the optimum block code for two transmit antennas and time domain coding. We show that the standard decoding algorithm results i...
