The Analysis On The Performance Of OFDM And The Realization Of 10KV Brand Band Power Line Modem

First this test analyses abstractly nonlinear distortion in power linechannel .Then the test realized emulational system of OFDM through MATLAB, adoptederror control coding of concatenation of convolutional codes and interlaced codes.In Gaussian noise channel and power line channel with adding noises only,thisemulational system calculate out relationship between bit error rates and signal tonoise ratios. Imitate separately with the conic of different coefficient, can controldifference in acceptable ranges .In the end the test shows the inner configurationsand functions of INT51X1 deeply ,and chose AC101L as the ethernet controller .Itdesigned 10KV broad band power line modem based on INT51X1 ,present the circuit designand coupling circuits design.
