Abstract :
An improved DC- and Nyquist-free error control line code based on the (8,4) extended Hamming code is proposed and its performance is analyzed. To increase its code rate, two blocks of error control codes are used as a line code with simple pre-coding. The proposed code can be well suited for high speed communication links, where DC- and Nyquist-free pulse format, channel error control, and low-complexity encoder-decoder implementations are required. As results of performance analysis, the proposed code shows null points at DC and Nyquist frequency and low levels of complexity. In addition, the proposed code shows wider eyewidth due to its Nyquist-free property
