A method and apparatus for pulse interference suppression, and a computer readable storage medium in a communication system are provided in the embodiments of the present invention. The method includes: judging a location where pulse interference occurs according to a power of a signal; and performing suppression processing on a data segment interfered by a pulse in the location. After judging that the pulse interference exists in the location, a receiver in the communication system discards the data segment interfered by the pulse in the location, and feeds back an indication that the data are not received.

Described is a low latency re-timer for systems supporting spread spectrum clocking. The re-timer comprises: a first clock frequency estimator to estimate a frequency of a receive clock (RX CLK) and to provide a first timestamp associated with a first clock that underwent spread spectrum; a second clock frequency estimator to estimate a frequency of a transmit clock (TX CLK) and to provide a second timestamp associated with a second clock that underwent spread spectrum; and a comparator to compare the first timestamp with the second timestamp.

The embodiments herein disclose a device and a method for controlling noise in a wideband communication system. In one embodiment herein, multiple microphones for receiving wideband audio signals are provided. A processor is configured to analyze each wideband audio signal received by each microphone. Further, unique signal patterns are generated based on each analyzed wideband signals for each microphone and the unique signal patterns are compared to detect any identical signal patterns. A controller is also provided for controlling gains of those microphones that are detected to be receiving wideband audio signal of identical signal patterns.
