Performance Analysis for Different Interleavers in Various Modulation Schemes With OFDM Over an AWGN Channel
The next generation wireless communications systems need to be of a higher standard in order to provide the customers with the multitude of high quality services they demand. In recent years, Orthogonal Frequency Division Multiplexing (OFDM) has been successfully used in terrestrial digital video broadcasting and showed it is a strong candidate for the modulation technique of future wireless systems. In order to investigate this, a simulation model was created and implemented using MATLAB. This paper focuses on the design of an OFDM system with the interleaver stage for a specific convolutional code operating with OFDM modulation. The interleaver is an important part in the design of a communication system.
