Abstract

The multicarrier modulations (MCM) became widely used and have been applied to wire and wireless transmission systems in recent years. This modulation techniques enable a near-perfect utilization of the provided frequency band on metallic cables and they also eliminate multipath propagation effect in terrestrial transmission. Mainly used implementations of MCM are Discrete MultiTone (DMT) and Orthogonal Frequency Division Multiplexing (OFDM). These approaches have also disadvantages, which have led to seeking new approaches to the implementation of the MCM modulation scheme. One of them is the Filtered MultiTone Modulation (FMT). In the article, the channel equalization in half-overlapped and non-overlapped FMT modulation will be compared.
