Gaussian and hyperbolic scattering channels in mobile OFDM systems : a preliminary study

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.
