Abstract:
1. A system for transmitting and receiving time-multiplexed signals, comprising: a transmitting arrangement including at least first and second OFDM transmitting devices which can each emit OFDM radio signals on at least one carrier frequency; an OFDM receiving unit located in a receiving region of the first OFDM transmitting device and the second OFDM transmitting device and capable of receiving the OFDM signals on each of the at least one carrier frequencies; and a context changing unit operatively coupled to the OFDM receiving unit for switching, for the duration of a data symbol in a frame of the first time-multiplexed signal on the first carrier frequency, to reception of the second time-multiplexed signal on the second carrier frequency, so that the OFDM receiving unit can receive an OFDM signal on another carrier frequency, so as to receive and evaluate the data symbol of the OFDM signal on the other carrier frequency to obtain the data coded therein, wherein this switchover by the OFDM receiving device is performed only outside a time window during which the useful symbol containing the useful data for reception of the selected program source are being performed.
