Patent ID: 8416836

Claim:
A Point-to-Point communication system, comprising: a millimeter-wave channel having a substantially flat channel transfer function between a first frequency of millimeter-waves and a second frequency of millimeter-waves, the two frequencies are separated by at least 500 MHz; a transmission system comprising an Orthogonal Frequency Division Multiplexing (OFDM) modulator configured to output an OFDM signal having a bandwidth of at least 100 MHz, and a radio transmitter having a substantially non-flat transmission transfer function denoting a difference of at least 4 dB between a highest magnitude and a lowest magnitude of a frequency response of the radio transmitter over the bandwidth of the OFDM signal, the radio transmitter configured to up-convert the OFDM signal into a millimeter-wave signal located between the first frequency and the second frequency, and to transmit the millimeter-wave signal via the millimeter-wave channel; and a reception system comprising a radio receiver having a substantially non-flat reception transfer function denoting a difference of at least 4 dB between a highest magnitude and a lowest magnitude of a frequency response of the radio receiver over the bandwidth of the OFDM signal, the radio receiver configured to receive the millimeter-wave signal via the millimeter-wave channel and down-convert the millimeter-wave signal into a reconstruction of the OFDM signal having a bandwidth of at least 100 MHz, and an OFDM de-modulator configured to compensate for the substantially non-flat transmission transfer function and the substantially non-flat reception transfer function, by de-modulating the reconstruction of the OFDM signal.
