New schemes for improving non data-aided symbol timing recovery for QAM receivers in flat fading channels

In this paper we present a digital symbol timing synchronization algorithm based on maximum likelihood theory. The algorithm can be totally implemented in discrete time either by a DSP processor, or in a VLSI chip. The channel average fade duration (AFD) and level crossing rates (LCR) are incorporat...
