Abstract

This invention puts forward a receiving and test method for a vertical lamination space time system based on adaptive modulation, which first of all tests channels with the modulation system reaching the maximum saturation, then tests the invalid channels with SN ration can't meet the lowest threshold, finally tests the residual sub-channels according to the principle of the priors with the SN ratio approaching to the threshold value after detection, which can make the tested SN ratio to satisfy the SN-ratio threshed value properly, so, channel resources can be used to the utmost.

Description

technical field

[0001] The invention relates to a reception detection method of a wireless communication system, in particular to a reception detection method of a vertical layered space-time system based on adaptive modulation. Background technique

[0002] The next-generation mobile communication system needs to support high-speed multimedia transmission services with different service quality requirements. The main index of high-speed transmission is spectrum efficiency, that is, under the premise of a given bit error rate and call drop rate, the maximum transmission rate that can be achieved within the unit bandwidth of a unit cell.

[0003] Bell Labs Vertical Layered Space-Time System (V-BLAST) is a technology first proposed by Bell Labs that uses multiple antennas at both the transmitting end and the receiving end. It is a technology that makes full use of airspace resources to improve communication systems Spectrum efficient communication technology. Under the usual...
