摘要: The invention belongs to the technical field of communication, and particularly relates a method for receiving an anti-time domain impulse interference signal coded OFDM system. directly performs IFFT/FFT operation noise reduction processing by using characteristic that high frequency zero-subcarrier is no data signal, which simpler than formula as shown in description calculating channel, wherein D matrix N x L , D(i,:)=F(n,:), 1 LS estimation pilot symbols description. occurrence ofsingular matrices avoided. Since there time will be entire band domain. At this time, desiredperformance cannot obtained only error correcting codes, scaling portions can reduce interference, but soft demodulation performance still not ideal. According method, treated equivalent together with noise, average power calculated replace variance demodulation, thereby improving system performance.
