Embodiment Construction

[0056] Some portions of the following description appear explicitly or implicitly in terms of algorithms and functions or symbolic representations that operate on data in a computer memory. These algorithmic descriptions and functional or symbolic representations are the means used by those skilled in the data processing arts to most effectively convey the products of their work to others skilled in the art. An algorithm, as referred to herein, is generally considered to be a self-consistent sequence of steps leading to a desired result. The steps are those requiring physical manipulations of physical quantities, eg, electrical, magnetic or optical signals, to be stored, transferred, combined, compared and otherwise manipulated.

[0057] Unless otherwise stated, it will be understood that throughout this specification, discussions utilizing terms such as "browsing," "computing," "judging," "replacing," "generating," "initiating," "outputting," etc. Refers to the acts and proc...

Abstract

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 utilizing 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.

Description

field of invention [0001] The present invention relates broadly to methods of data transmission in multiple-input multiple-output (MIMO) systems, to transmitters in MIMO systems, to computers having stored thereon computer code instructing MIMO systems to perform methods of data transmission in MIMO systems Readable data storage medium, to a method of processing data received in a MIMO system, to a receiver in a MIMO system, and to a computer-readable computer having stored thereon computer code instructing a MIMO system to perform a method of processing data received in a MIMO system Read data storage media. Background technique [0002] Wireless communication systems have been used to carry voice traffic and low data rate non-voice traffic. 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 may be used to transport streami...
