Example Embodiment

[0050] At present, in the multi-antenna BLAST communication system using nonlinear detection according to the prior art, the principle of rate control is as follows: image 3 Shown.

[0051] In this system, the i-th detecting antenna K i The calculation method of the equivalent signal-to-noise ratio is

[0052] K i = arg min j | | ( G i ) j | | 2

[0053] Where P 1 Is the total power of the signal transmission at the transmitting end of the system, δ 2 Is the noise variance at the receiving antenna.

[0054] The calculated equivalent signal-to-noise ratio is fed back to the sending end by the feedback ch...

Abstract

The invention provides a rate control method for multi-antenna signal which includes steps: a receiver terminal determines detection order of each transmitting antenna signal; equivalent signal-to-noise ratio of each transmitting antenna is calculated and is feed back to a transmitter terminal; the transmitter terminal determines encoding and modulation parameter of each antenna according with equivalent signal-to-noise ratio feed back by the receiver terminal, encodes and modulates to date stream and transmits; the receiver terminal detects received date stream and processes disturbance recovery, disturbance cancellation. The method provided by the invention takes full consideration of error propagation in equivalent signal-to-noise ratio calculation, thereby, equivalent signal-to-noise ratio precision is increased, validity and reliability of the transmitter terminal in encoding and modulation parameter selection are improved, and system performance is increased. At the same time, calculation complexity of the method has a much smaller increase, and prior system frame is not changed basically, thus, the method has more better practical value.

Description

Technical field [0001] The present invention relates to the field of information transmission in a multi-antenna communication system, and in particular, to a multi-antenna signal rate control method. Background technique [0002] (1) BLAST technology and multi-antenna signal detection method [0003] The use of multi-antenna spatial multiplexing BLAST technology can effectively increase the data transmission rate under the condition of limited spectrum resources. [0004] The existing BLAST detection methods are divided into linear detection (including zero-forcing detection ZF, minimum mean square error detection MMSE, etc.) and nonlinear detection (including zero-forcing plus interference cancellation detection ZF-SIC, and minimum mean square error plus interference cancellation detection MMSE- SIC etc.). Compared with linear detection, nonlinear detection methods can effectively improve system performance at the expense of increased computational complexity. At the same time,...
