Abstract

What are the modulation/demodulation schemes that are suitable tor cable or wireless high speed or broadband data link, between 1 Mbps to 30 Mbps? The recent adoption of modulation schemes such as OFDM, 8-VSB, OAM, for Digital Television broadcast (DTV), Asymmetrical Digital Subscriber Lines (ADSL), and Cable Modem (CM) for Internet access, is poss'1ble because of the increase bit/Hz in these modulations over conventional modulation schemes. These modulation/demodulation schemes could also offer similar advantages to dedicated data link applications such as home-networking using cable or wireless medium. This report document the project implementation of Quadrature Amplitude Modulation as the modulation I demodulation scheme for a Cable/Wireless Modulation/Demodulation Frontend Module For High Speed/Broadband Data Link. A hardware prototype was constructed with a 10Base-T Module interface to the OAM modulator/demodulator module through a QAM-16 symbol mapper/decoder.
