Performance Analysis of Multiple Access 60 GHz System Using Frequency-shifted Gaussian Pulse and Non-carrier PSWF Pulse

In this paper, a kind of impulse radio (IR) 60 GHz pulse based on Prolate Spheroidal Wave Functions (PSWF) is proposed. The capacity and performance for multiple access 60 GHz communication system based on carrier pulse and impulse radio pulse are analyzed separately. Both frequency-shifted Gaussian pulse and Prolate Spheroidal Wave Functions (PSWF) pulse are considered and devised according to the federal communication commission (FCC) power constraints. Pulse position modulation (PPM) with time hopping spread spectrum (THSS) is employed in the multiple access 60GHz communication system. The channel capacity and error probability for 60GHz communication system with different pulse waveforms over additive white Gaussian noise (AWGN) channel are compared and analyzed. The simulation results showed that the PSWF pulse 60GHz system with has better channel capacity and error probability performance than frequency-shifted Gaussian pulse 60GHz system.
