Abstract

This paper shows results of link level simulations conducted to evaluate performances of spatial and temporal equalizers (S/T-equalizers) using field measurement data. The spatial and temporal equalizer discussed has a configuration expressed as a cascaded connection of adaptive array antenna and maximum likelihood sequence estimator (MLSE): each of the antenna elements has a fractionally spaced tapped delay line (FTDL), and the MLSE has taps covering a portion of channel delay profile. Bit error rate (BER) performance of the S/T-equalizers, including that in the presence of co-channel Interference (CCI) are presented. Performance sensitivity to symbol timing offset is also investigated. Major conclusions of this paper are that allocating more taps to the spatial domain is more effective than to the time domain when the total number of taps is fixed, and that increasing the FTDL length is effective in reducing performance sensitivity to timing offset.
