Patent ID: 8543147

Claim:
A radio communication system comprising: a transmission system including a first radio communication device configured to superimpose a first signal sequence and a first delay signal sequence which is generated by delaying the first signal sequence, and transmit a first superimposed signal including the first signal sequence and the first delay signal sequence, a second radio communication device configured to superimpose a second signal sequence and a second delay signal sequence which is generated by delaying the second signal sequence by a delay amount different from a delay amount of the first delay signal sequence, and to transmit a second superimposed signal including the second signal sequence and the second delay signal sequence using the same frequency band as the first signal sequence in the same time range as the first signal sequence, and a notification unit configured to notify the radio terminal of first delay information about the first delay signal sequence and second delay information about the second delay signal sequence; and a radio terminal including a receiver configured to receive the first and second superimposed signal sequences from the transmission system in the same time range, and to receive the first and second delay information, and a separation processor configured to execute separation processing to separate the first and second signal sequences received by the receiver, wherein the separation processor combines the first signal sequence and the first delay signal sequence in accordance with the notified first delay information, and also combines the second signal sequence and the second delay signal sequence in accordance with the notified second delay information, when executing the separation processing.
