Therefore, the proposed receiver is able to reduce packet miss rate and false alarm rate while robust to a severe channel condition, and achieve fast and accurate signal quality detection.

Aspects in particular need of attention include data transmission by countries, assurance of data quality, and the processing and analysis of data, including timely signal detection and action.

The autocorrelation pitch detection algorithm is the key technique for speech signal processing, and its efficiency directly affects the quality of real-time speech processing.
