Performance of Block Turbo Coded OFDM with 16-QAM Modulation in Rayleigh Fading Channel
نویسندگان
چکیده
In this contribution the performance of Reed-Solomon (RS) Block Turbo Coding (BTC) is studied in a 16-QAM modulated OFDM system when operating on a Rayleigh fading channel. BER and PER performances are shown and compared to the performance of Convolutional Turbo Coding (CTC). BTC proves to mitigate the irreducible error floor that limits the performance of CTC at high signal-to-noise ratios (SNR).

Orthogonal frequency-division multiplexing (OFDM) is a method of encoding digital data on multiple carrier frequencies. The data are sent over parallel sub-channels with each sub-channel modulated by a modulation scheme such as BPSK, QPSK, 16 QAM etc. The advantage of OFDM is its ability to cope with severe channel conditions compared to a single carrier modulation scheme but still maintaining ...

In this paper, the application of Multi Binary Turbo Codes (MBTCs) to two multicarrier modulation techniques used for transmission in the flat radio fading channel is studied. Thus, the performance of the coded versions of Orthogonal Frequency Division Multiplexing (OFDM) and of its wavelets based version (WOFDM) is evaluated under several simulation scenarios. These scenarios take into account...
