In cellular systems, the performance degradation caused by multi-path fading may be reduced by applying diversity antennas at base stations (BS) to recover the signals received on uplink. But the characteristics of the fading signals received on different antennas may be somehow correlative when the distance between antennas are constrained, thus the anticipated diversity gain may not always be obtainable. This paper proposes a modified multi-path uplink channel model based on the local scattering phenomena aroused around the mobile station. The effects of different channel model setups on the system performance are analyzed by purposeful simulations in the frame of the channel model proposed. Furthermore, this paper also proposes an effective numeric approach to calculate the BER performance in correlated Gaussian fading channel, given the correlation matrix of the channel.
