The performance of two adaptive equalization techniques applicable to ARTM Tier-1 waveforms over a frequency selective multipath channel is summarized. Adaptive equalization based on the constant modulus algorithm (CMA) and the decision-directed minimum mean squared error (DF-MMSE) concept are shown to be effective in reducing the bit error rate in the presence of frequency selective multipath interference. The performance of the DF-MMSE equalizer is slightly better than the CMA equalizer. Implementation trade-offs between the two types of equalizers are also discussed.Sponsors
