Abstract
The paper describes the transmission of 32-QAM signals in an OFDM system with 128-point IFFT at transmitter and FFT at receiver. The channel over which transmission will take place is AWGN channel. Cyclic prefix for OFDM is calculated for improving bandwidth efficiency of the system. First, the symbol rate (SER) of coded OFDM system with transmission of BPSK signals in an OFDM system with 64-point IFFT at transmitter and FFT at receiver is plotted as a function of SNR via simulation in MATLAB and then the result is compared with coded OFDM system's SER plot, where the coding is provided by Trellis encoding at the transmitter accompanied by viterbi decoder at the receiver side.
