Problems solved by technology

However, the above method cannot be flexibly adapted to each emission stream of multiple stream data, since the same upscaling matrix (i.e., same in terms of dimensionality and density) is used for each of the multiple streams, and the expansion factor is fixed equal to Number of transmitting antennas

Embodiment Construction

[0063] Some parts of the following description explicitly or implicitly appear in the algorithms and functions or symbolic representations that operate on the data in the computer memory. These algorithm descriptions and functions or symbolic representations are the means used by those skilled in the data processing field to most effectively convey their work results to other skilled in the art. The algorithm referred to in this article is generally regarded as a self-consistent series of steps that can bring expected results. These steps are those required physical operations of physical quantities, for example, electrical, magnetic, or optical signals can be stored, transmitted, combined, compared, and other operations.

[0064] Unless specifically stated otherwise, it is obvious from the following that it can be understood that through this specification, the discussion using terms such as "browse", "calculate", "judgment", "replace", "produce", "start", "output", etc. Refers t...

Abstract

A method for data transmission in a multiple input multiple output (MIMO) system, the method comprising, 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 ones of the input data streams; and performing space time encoding for transmitting the LDPC encoded input data streams over a plurality of antennas.

Description

Technical field [0001] The present invention broadly relates to a method of data transmission in a multiple-input multiple-output (MIMO) system, to a transmitter in a MIMO system, and to a computer on which computer code instructing the MIMO system to perform the method of data transmission in the MIMO system is stored A readable data storage medium relates to a method of processing received data in a MIMO system, relates to a receiver in a MIMO system, and relates to a computer code stored thereon instructing the MIMO system to execute the method of processing received data in the MIMO system Computer readable data storage medium. Background technique [0002] Wireless communication systems have been used to transmit voice services and low data rate non-voice services. Current wireless communication systems can also transmit high-data-rate multimedia services, such as video, data, and other types of services. Multimedia Broadcast and Multicast Service (MBMS) channels can be used...
