The 60 GHz band is of much interest since this is the band in which a massive amount of spectral space (5 GHz) has been allocated unlicensed worldwide for dense wireless local communications. Orthogonal Frequency Division Multiplexing (OFDM) has gained much popularity in the field of wireless communication because of its ability to transfer the data at higher rate, high bandwidth efficiency and its robustness with regard to multipath and delay. In this paper, the authors consider a Discrete Cosine Transform (DCT)-based OFDM system for calculating bit error rate with Additive White Gaussian Noise (AWGN) channel and Saleh-Valenzuela (SV) channel model at 60 GHz. The BER is calculated for signaling formats BPSK and the performance of DCT based OFDM is analyzed at 60 GHz.
