This MATLAB function performs OFDM modulation on the frequency-domain input data subcarriers, inSym, using an FFT size specified by nfft and cyclic prefix length specified by cplen. The ofdm matlab code for the above block schematic is provided below for download. OFDM transmitter in this example consists of FEC encoder, BPSK modulator and 256 point IFFT. OFDM receiver part consists of FFT, BPSK demodulator and viterbi decoder. This code basically computes the BER of an OFDM system. The ifft size is 64 .16-QAM is the modulation Technique and convolution encoding rate 1/2 is used as the coding scheme.

By using this technique reserved tones can be used to minimize the PAPR.this method is used for multicarrier transmission and also shows the reserving tones to reduce the PAPR.this technique is depend on amount of complexity.when there is number of tones is small rduction in PAPR may represent non negligible samples of available bandwidth.advantage of this tone reservation is very positive
