Further, the data is modulated at the transmitter using a second signal constellation pattern to obtain a second data symbol. Then, the second data symbol is transmitted to the receiver over a second diversity path. Finally, the received first and second data symbol are diversity combined at the receiver.The invention further relates to a transmitter and a receiver embodied to carry out the method of the invention.

    摘要: An ARQ (re-) transmission method of transmitting data in a wireless communication system wherein data packets are transmitted from a transmitter to a receiver, using a first transmission and a second transmission based on a repeat request. The method comprises the steps of modulating data at the transmitter using a first signal constellation pattern to obtain a first data symbol. The first data symbol is transmitted as the first transmission to the receiver using a first diversity branch. Further, the data is modulated at the transmitter using a second signal constellation pattern to obtain a second data symbol. Then, the second data symbol is transmitted as the second transmission to the receive over a second diversity branch. Finally, the received first and second data symbol data symbol are diversity combined at the receiver. The invention further relates to a transmitter and a receiver embodied to carry out the method of the invention.

    摘要: An ARQ transmission method in a communication system, wherein data packets comprising modulation symbols are transmitted based on an automatic repeat request and subsequently combined with previously received data packets. The symbols of the transmitted data packets are modulated in a mapping entity employing at least a first and second signal constellation. The method further comprises the step of obtaining the second signal constellation from the first signal constellation by exchanging a logical bit position and/or inverting a logical bit. The invention further relates to a corresponding transmitter and receiver.

    摘要: The invention provides a method of interleaving a source data stream using an interleaver pattern in a transmitter. A mother interleaver pattern and an interleaver parameter are accessed. The mother interleaver pattern is modified using said interleaver parameter. Then, the modified interleaver pattern is applied in the transmitter for interleaving the source data stream. The interleaver parameter used by the transmitter for modifying said mother interleaver pattern differs from the interleaver parameter used simultaneously by at least one other transmitter that transmits data at the same time on the same channel. The invention further provides a corresponding deinterleaving method. By decorrelating the interleaver processes in the different streams, the inter-stream interference is reduced.
