| Abstract: | The principle and method of HDB3, which is widely used in the E1 transmission, are discussed in detail in this paper. The coding implementation of the HDB3 signal using FPGA device is presented specifically. The results show that this method has more advantages than ASIC in structure and volume, and it is more convenient in debug. |
