Online published on 4 June, 2019. Abstract Performance of any communication system depends on the characteristic of the channel and the presence of noise. Channel distortion is deterministic in nature, but noise behavior is random and cannot be predicted in advance(beforehand). To reconstruct the signal on the receiver side, use of equalizer can be one of the solution to compensate distortion by the channel and minimize the effect of noise. This paper has proposed fractionally spaced equalizer for custom architecture of ADSL modem. The obtained result in the paper shows that there is an improvement in the performance of ADSL modem with the use of fractionallyspacedequalizer because it is immune to the phase change. The obtained results are compared with symbol-spaced equalizer for different lengths and gauge of the wire. MATLAB 2015 is used for the simulation of code and implementation of ADSL modem is done on FPGA, to calculate the amount of power consumption. Top Keywords Modem, adsl, blocks, speed. Top |
