| Abstract | An equalisation concept for the novel radio access scheme enhanced data rates for GSM evolution (EDGE) is proposed, by which high performance can be obtained at moderate computational complexity. Because high-level modulation is employed in EDGE, optimum equalisation as performed in most GSM receivers is too complex, and suboptimum schemes have to be considered. It is shown that delayed decision-feedback sequence estimation (DDFSE) is a promising candidate. For various channel profiles, approximations for the bit error rate of DDFSE are given and compared with simulation results. It turns out that a discrete-time allpass prefilter creating a minimum-phase overall impulse response is indispensable for obtaining a favourable tradeoff between performance and complexity. Additionally, the influence of the receiver input filter is investigated |
