1. A method, comprising: mitigating spectral leakage in DMT (Discrete Multi-Tone) receivers, wherein mitigating spectral leakage comprises designing a receiver window to reduce edge effects of an IFFT/FFT transformation; applying the receiver window to a received signal in a time domain; using a FFT to convert the received signal into a frequency-domain symbol; reducing the length of the receiver window by not including 0 as a first coefficient or 1 as a last coefficient in receiver window coefficients; multiplying samples in a last part of a prefix of the received signal by the receiver window coefficients to generate a first result; multiplying the samples in the last part by the receiver window coefficients subtracted from 1 to generate a second result; adding the first result and second result to generate modified samples; and substituting the modified samples into the last part of the received signal.
