Baseband transceiver design of a 128-kbps power-line modem forhousehold applications

摘要

Communication using power line as a medium provides a convenientnand inexpensive way for data transmission and control signaling in thenhouseholds. In this paper, we introduce a power-line channel model asnwell as architecture of a spread-spectrum baseband transceivernintegrated circuit (IC) for a power-line modem. The modulation andnspreading scheme used in the proposed transceiver is M-ary bi-orthogonalnkeying (MBOK). This transceiver runs at a chipping rate of 256 kHz andnprovides 128-kbps data rate. Simulation results as well as FPGAnemulation verify the effectiveness of the proposed architecture fornhousehold data communication
