Performance evaluation of different OFDM transmission schemes

Orthogonal Frequency Division Multiplexing (OFDM) has been one of the well distinguished technologies in wireless communication in terms of its robustness and high delivery speed. In this paper, we have performed an effective comparison on the basis of various OFDM transmission schemes and our proposed scheme to examine the most effective one in terms of less amount of error. First of all, we have compared through the study of past OFDM schemes and inferred that two previous schemes Structured Compressive Sensing (SCS) and Compressive Sensing (CS) aided TDS-OFDM provide maximum spectral efficiency and also supports 256 QAM. However, on further comparison through our simulation we have concluded that our proposed scheme is better than previous schemes in terms of it´s error performance measuring parameters like BER, MSE.
