    摘要: In a TDS-OFDM communications system, within a frame time, a transmitted signal comprising a preamble, a downlink sub-frame, and an uplink sub-frame. Within the downlink sub-frame, interposed between sub-frames are guard intervals comprising known sequences. The known sequences are used for an estimation of a received power. A method comprising the step of using a guard sequence in a guard interval of OFDM symbols of the received TDS-OFDM signals in the downlink to estimate a received signal power or an interference power is provided.
