Abstract: |
A signal transmitting and receiving method for the orthogonal frequency division multiplexing system includes such steps as sub-carrier mapping of the frequency domain transmission sequence composed of the data to be transmitted and piloted, respectively and repeatedly copying the transmission sequence at both ends of the transmission sequence to extend it, adding frequency domain window, IFFT transforming, adding cycle prefix, time domain filter, transmitting it to receiving terminal, channel estimating by the method based on IFFT at the receiving terminal, and simple in-band and out-of-band packing of the data and the estimated channel frequency domain response value to obtain the final OFDM demodulation data. |
