Abstract: Digital Communication systems make the process feasible for sustaining large amount of noise data and avoid distortions mainly generated through various techniques. However, a common problem with commonly used techniques, such as Pulse Coded Modulation (PCM) and Linear Delta Modulation (LDM), is that they negatively affect the communication process by causing quantization error, slope overload distortion, and granular noise. This paper describes the DPCM technique which solves the quantization error faced by the PCM. The performance optimization has been achieved using optimization tool of MATLAB.
Keywords: Differential Pulse Coded Modulation, quantization error, optimization error, PCM.
