Analog-Digital Hybrid Modulation for improved efficiency over Broadband Wireless Systems

SEMINAR TOPIC ON Analog-Digital Hybrid Modulation : This document is intended to provide the means to eliminate inherent component of quantization noise in digital communications, rather than conventional making it minimal. This is a new concept of signal is called signal Code modulation(SCM) Technique. The primary analog signal is represented by: one specimen, quantized and coded digital and analog component, which is a function of quantization part of a digital sample. Although the benefits of The system has two sites offer the advantages of both analog and digital signage. The presence of analog residual to improves the system performance when excess Channel SNR is available. The digital component provides Increased SNR and allows it possible for coding to be used to achieve near error-free transmission.
