Problems solved by technology

At present, the 3GPP RAN1 conference has proposed a requirement for a coding scheme with higher spectral efficiency, which makes the 2×2Golden coding suitable for low-dimensional (2×2) MIMO communication systems unable to meet this requirement
[0003] In addition, the channel bandwidth allocated in the latest standard is about 20MHz. In order to achieve a bit rate of hundreds of megabits per second, the antenna configuration mode of 2 transmitting antennas and 2 receiving antennas in the MIMO communication system can no longer meet the demand. Therefore, , the antenna configuration mode combining more transmit / receive antennas (4 or more) with Orthogonal Frequency Division Multiplexing (OFDM) has begun to attract widespread attention

Abstract

The invention provides a method and device for encoding data in network equipment of a 2M*2M multiple-input and multiple-output communication system. Particularly, a high-dimensional Golden encoding matrix is used for encoding symbols which are modulated; and the high-dimensional Golden encoding matrix is generated by a formula shown in the specification, wherein i=1, 2; j=1, 2; M=2, 3, 4...; and beta=1+j(1-theta).

Description

technical field [0001] The present application relates to a multiple-input multiple-output (MIMO) communication system, in particular to a method for generating a high-dimensional Golden encoding matrix suitable for a high-dimensional MIMO communication system, and a method and device for encoding data using the high-dimensional Golden encoding matrix . Background technique [0002] Golden coding is a full-rate full-diversity 2×2 linear sparse space-time block code. In the 3GPP RAN1 meeting, a solution to apply Golden coding to multimedia multicast services in wireless networks was proposed (see "R1-090062, Open-loop Spatial Multiplexing with pre-coding decorrelation for LTE-A MBMS, Alcatel Shanghai Bell , Alcatel-Lucent"). At present, the 3GPP RAN1 conference has proposed a requirement for a coding scheme with higher spectral efficiency, which makes the 2×2Golden coding suitable for low-dimensional (2×2) MIMO communication systems unable to meet the requirement.
