Abstract
Inter-carrier interference power PICI of Gaussian and hyperbolic scattering channels in a mobile orthogonal frequency division multiplexing (OFDM) system using their angle-of-arrival (AoA) probability density functions (pdf) is estimated. The PICI difference of the two channels is estimated and plotted as functions of ( , ζ), ( ,) and ( , fdTs). Experimental PICI difference for = 0, ζ = 0 and fdTs = 0.05 is obtained and plotted with the simulated results for comparison purposes. The ICI power is also plotted against (fdTs,), (fdTs,ζ), and (ζ,) for specific values of . Closed-form bit error rate (BER) expressions of OFDM communication systems in an added white Gaussian noise (AWGN) and Rayleigh fading environments using bipolar phase shift keying (BPSK), OFDM-BPSK, are derived.
