Abstract
In order to solve the difficult problem that the AD sampling frequency is restricted in high-speed communication, this pa- per introduces a modulation and demodulation technology based on undersampling. The paper presents the algorithm of non-uniform fractional spaced equalizer and the design method based on FPGA,and finally gives the main test result,including three kinds of BER curves for different SNRs at the speed of 2 MHz,8 MHz and 34 MHz. Compared with traditional oversampling method,this technology is easy to implement and saves the chip resource, and has the characteristics of good practicability, good performance, stable and reliable synchronization etc.关键词
