Abstract

In this paper we proposed an algorithm using symbol- overlapping, redundant transforms for both, transmitter and receiver. We show that a combination of a low-delay cosine- modulated filter bank at the transmitter and an optimized filter bank at the receiver performs as good as the Discrete Multitone solution, but with much smaller latency time. For channel equalization Zero-Forcing and MMSE methods are used. Different methods of redundancy insertion used for a better channel equalization are discussed. Due to better stopband attenuation of the basis filters modulated filter banks show less sensitivity to Intersymbol and Intercarrier Interference and narrowband interferers.
