Abstract

The waveform shaped multicarrier modulation (MCM) is considered for high capacity data transmission in digital microwave radios. The degradations of the MCM system performance caused by the multipath fading of the line-of-sight (LOS) radio channel are investigated. A 512-carrier system with a data rate of 155 Mb/s is described and simulated. The signal-to-interference ratio and the signature curve of the MCM system are evaluated by using Rummler´s (1979) channel model. Simulations show the robustness of the system in the multipath fading channel. The simulated results for adaptive channel estimation are also given
