Abstract: The invention is directed to a system and method of regulating a slicer for a communication receiver. A zero-crossing accumulator receives a slicer output from the slicer and accordingly determines a zero-crossing length of the slicer output. A threshold decision unit regulates at least one threshold value of the slicer according to the zero-crossing length.

Abstract: A communication receiver and a receiving method are disclosed. An analog front-end device samples a receiving signal and generates a sampled signal. A signal detector detects presence of the receiving signal according to the sampled signal. A symbol timing recovery (STR) unit determines an optimal symbol sampling point according to a zero-crossing point of the sampled signal when the receiving signal is present, and then generates a recovered symbol based on an optimally chosen sampled value according to the optimal symbol sampling point.

Abstract: A method for frequency compensation includes the following steps: detecting and checking if a desired frequency falls within a first detectable frequency range delimited by an initial frequency and a first specific frequency; and when the desired frequency exceeds the first detectable frequency range, utilizing a first frequency compensation step with a step size greater than a size of the first detectable frequency range for shifting the initial frequency to a first adjusted frequency beyond the first specific frequency in a first direction.

Abstract: A method and system of receiving data with enhanced error correction is disclosed. One or more reliability bits associated with each received data bit are generated, for example, by a soft-decision slicer. Subsequently, one or more errors of the data bits may be corrected according to the associated reliability bit(s).

Abstract: Method and apparatus for deciding a channel impulse response for an OFDM system are provided. First, a channel frequency response is generated by using a plurality of pilot tones of a signal. A channel impulse response is generated by applying the IFFT to the channel frequency response. A plurality of selected channel taps are derived by comparing a plurality of channel taps related to the channel impulse response with a reference threshold. Finally, the channel impulse response is generated by calculating channel impulse respose according to the selected channel taps. This method calculates the channel impulse response in time domain and frequency domain so that the calculation complexity can be reduced, and the system efficiency can be enhanced.
