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. 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. But the major hurdle is high PAPR leading to inter-modulation distortion and out-of-band spectral growth. Constant envelope OFDM transforms the OFDM signal, to a signal with nearly zero dB PAPR. The PAPR performance of conventional OFDM system improves with constant envelope OFDM system. CE OFDM scheme provides PAPR to 0 dB; this paper analyzes the performance of CE OFDM on grounds of BER. A constant envelope OFDM system is considered 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 signalling format BPSK and the performance of CE OFDM is analyzed at 60 GHz
