Abstract
A system and method are provided for processing symbols for transmission. The method involves producing a set of 2K outputs that include K real components and K imaginary components from K complex symbols, performing a Fourier transform operation on the 2K outputs to produce 2K Fourier transform outputs, pulse shaping the 2K Fourier transform outputs by multiplying each of J of the 2K Fourier transform outputs with a respective one of J non-zero coefficients, where J is odd, and K≤J≤2K−1, performing an inverse Fourier transform operation on the J pulse shaped outputs to produce an inverse Fourier transform output; and outputting the inverse Fourier transform output. The approach has the advantage of avoiding self-interference, with the result that better BLER performance may be possible. The approach is applicable to any modulation order without bandwidth expansion. Flexibility is provided through a trade-off between PAPR vs. spectrum efficiency.
