Abstract

A receiver () for performing timing recovery over at least one complex channel at low or less than zero SNR (signal power to noise power, in dB) has at least one receive element such as an antenna, an analog-to-digital converter(ADC), a fractional interpolation filter, a matched filter, and a timing correction loop. The timing correction loopselects a minimum mean square error from the output of the matched filterto determine a timing signal output to the interpolation filter, and provides one-bit weights to the matched filter. Preferably, the timing correction loopincludes a magnitude detector, a moving average filter, and a timing error detectorthat outputs an integer m and fractional μ timing factor to the interpolation filter. Within a phase correction loopis a maximum likelihood channel estimatorand a phase error detectorthat controls a phase rotatordisposed between the ADCand the interpolation filter
