Implementation of improved parallel data processing algorithm in FPGA

1. Introduction In the process of signal processing, we usually convert analog signal into digital signal for processing or transmission. The original data is collected by sampling method, and the analog signal is converted into digital signal through a / D conversion. However, due to the large number of code bits, such digital signals occupy […]
