摘要： A method for data transmission in a multiple input multiple output (MIMO) system, a transmitter in a MIMO system, a computer readable data storage medium having stored thereon computer code means for instructing a MIMO system to execute a method for data transmission in the MIMO system, a method for processing received data in a MIMO system, a receiver in a MIMO system and a computer readable data storage medium having stored thereon computer code means for instructing a MIMO system to execute a method for processing received data in the MIMO system are provided. The method for data transmission comprises receiving multiple input data streams; performing low density parity check (LDPC) encoding of the input data streams utilising a parity check matrix, wherein the parity check matrix comprises a plurality of sub-parity check matrices for encoding respective associated ones of the input data streams and performing space time encoding for transmitting the LDPC encoded input data streams over a plurality of antennas; wherein the performing of the LDPC encoding of the input data streams comprises generating one or more connection matrices, each connection matrix for injecting information of one of the input data streams into the encoding of another one of the input data streams, and wherein said each connection matrix is a zero matrix if a lowest parity check protection level based on the sub-parity check matrix for said one of the input data streams is equal to or lower than an assigned parity check protection level for said one input data stream, and a non zero matrix otherwise.
