Abstract:
A transmitter for transmitting data to a receiver of a wireless communication network is disclosed. The wireless communication network includes a plurality of resource elements, and at least a subset of the plurality of resource elements is shared by a plurality of transmitters for transmitting data from the plurality of transmitters to the receiver. The transmitter includes at least one antenna, an encoder and a transceiver coupled to the encoder and to the antenna. The encoder receives a data element to be transmitted to a receiver of the wireless communication network, and maps the data element to a codeword obtained by selecting at least one vector from a unique set of vectors. The unique set of vectors is exclusively assigned to the transmitter, and each vector includes a plurality of symbols. Each symbol is to be transmitted over a resource element of the wireless communication network. The transceiver transmits via the antenna the codeword on the subset of resource elements, the codeword representing the data element and identifying the transmitter at the receiver.
