Abstract
In a modulation system an efficient modulation at a master station and allows great flexibility in clients, from simple 2 bit/symbol single-channel modulation and demodulation to multi-channel multiple-bit modulation. The present invention also permits selection of the frequency band to use for transmission, thus dealing effectively with channel nulls and no channel equalization is required. The present invention is a useful technique for short-distance moderate-rate multi-drop networking, such as multi-channel home-telephone for Voice over IP(VoIP).
