Novel precoding algorithm for VDSL-2

We propose a novel concept of symbol relocation for the improvement of received signal power in diagonal precoder. In the past, many precoding algorithm have been proposed, they all suffer either in terms of low bit rate, high complexity and less received signal power. The proposed symbol relocation concept in diagonal precoder gives high data rate with high received signal power. Complexity of the diagonal precoder has been checked using digital signal processor starter kit -6713, a 32 bit floating point digital signal processor. Our results shows that there is improvement in received signal power by 20 dB while maintaining the same bit rate with low complexity of the system.
