<p>A matched filter and receiver is provided to delete the tap coefficients of a matched filter used in an OFDM receiver. In the matched filter and receiver, a transmitting signal is generated by using a symmetric series(Y) obtained from C[k]=exp[j*À*M/N*(k+0.5)9^2], where X=[0, C[N/2], C[N/2+1], ...,C[N-1], 0, 0, ..., 0, C[0], C[1], ..., C[N/2-1]], and Y = inverse FFT(X) as a base symbol. The matched filter, which detects the signal, reduces the number of multipliers by using the coefficient symmetric property.</p> |
