Simple Algorithms for Estimating the Symbol Timing Offset in DCT-Based Multicarrier Systems

Simple Algorithms for Estimating the Symbol Timing Offset in DCT-Based Multicarrier Systems

Multicarrier modulation based on discrete cosine transform (DCT-MCM) is a candidate technique for future wireless communication. DCT-MCM provides a better usage of the spectrum, allowing for much lower out-of-band radiation than conventional OFDM. In this paper, we address the problem of correcting...
