Abstract
An Orthogonal Frequency Division Multiplexing (OFDM) receiver system for improved pilotless detection of symbol boundary of a received OFDM symbols using M-ary Phase Shift Keying (M-PSK) modulated carriers as a cost function. The OFDM receiver includes a symbol boundary detection block that detects a symbol boundary of the received OFDM symbols. The symbol boundary detection block detects the symbol boundary by computing a cost function of a second order moment of the M-PSK modulated carriers. The receiver system detects the symbol boundary for unknown information on the received OFDM symbols.
