1. A communication receiver, comprising:
- an analog front-end device configured to sample a receiving signal and generate a sampled signal;
a signal detector configured to detect presence of the receiving signal according to the sampled signal; and
a symbol timing recovery (STR) unit configured to determine an optimal symbol sampling point according to a zero-crossing point of the sampled signal when the receiving signal is present, the STR unit generating a recovered symbol based on an optimally chosen sampled value according to the optimal symbol sampling point;
wherein the analog front-end device is a slicer configured to map a sampled value of the receiving signal to the sampled signal having multiple levels.

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.
