Patent ID: 7286612

Claim:
A method of transmitting data from a transmitter to a receiver in a radio system, comprising: channel-coding the data using selected channel-coding; dividing the channel-coded non-interleaved data into signals with different contents, to be transmitted via at least two different transmitter antennas; providing the signal to be transmitted via each transmitter antenna with an identifier, by means of which identifier the signals transmitted via different transmitter antennas are distinguishable from each other in the receiver; transmitting the signals to the receiver using different transmitter antennas; detecting the signal transmitted via each transmitter antenna with a receiver receiving each transmitter antenna in the receiver, and combining the detected signals into received channel-coded non-interleaved data; decoding the channel-coding of the received channel-coded non-interleaved data; the receiver attenuating interference utilizing the decoded data, and re-encoding the decoded data in the receiver using the channel-coding used in the transmission; further comprising, for interference attenuation: estimating multiple access interference for each transmitter antenna by utilizing the re-encoded data; and cancelling the multiple access interference from the received signal of each transmitter antenna; re-detecting with receivers the received signals of each transmitter antenna, purged from the multiple access interference; and combining the detected signals into received channel-coded non-interleaved data; and finally, decoding the channel-coding of the received channel-coded non-interleaved data.
