The 3GPP LTE standards and mainly concentrates on the LTE 8 OFDM PHY layer. A MATLAB model based on LTE 8 PHY baseband is built for simulation and performance evaluation. All mandatory blocks in the 802.11aOFDM-PHY specification are included: Randomization, FEC, adaptive modulation, and IFFT/FFT. An additive random Gaussian channel is implemented and Peak to Average Power ratio is reduced using clipping and filtering and commanding model at the transmitter end and it is quantified using CCDF analysis.
