Problems solved by technology

However, considering that the indicator signal needs to be more accurate than the business information, it is necessary to encode the indicator signal more reliably, which will waste precious channel resources
Moreover, in order to ensure real-time performance, the indicator signal cannot be interleaved in the time domain for a long time, which further reduces the accuracy of the indicator signal

Embodiment Construction

[0031] Various preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] The method of the invention provides an indication method for antenna selection information that does not need to be fed back in a space division multiplexing MIMO system, does not occupy extra channel bandwidth, has high accuracy, and can meet the real-time requirements of channel changes.

[0033] The technical content of the inventive method comprises the following steps:

[0034] Step 1: Design mutually orthogonal pilot sequences at the transmitter. Each transmitter antenna corresponds to two pilots, which are divided into main pilot and auxiliary pilot. The main pilot corresponds to the transmitting antenna to send service signals, and the auxiliary pilot corresponds to the transmitting end. The antenna does not send service signals; establish the corresponding relationship between the pilot and the antenna of the transmit...

Abstract

This invention discloses one zero zone self-adaptive antenna selection and indication method, which comprises the following steps: turning the emission end signal metric device as down signal matrix estimation for antenna selection; the said emission end determines each antenna guide frequency sequence by antenna selection results; the said emission machine sends the frequency sequence and signalset frame; the said receive end receives signals from emission end using main and aid identification devices and received signals for main and aid frequency matching.

Description

technical field [0001] The invention relates to a method for indicating antenna selection in a multiple-input multiple-output (MIMO) wireless communication system, in particular to a method for indicating antenna selection information in realizing adaptive space channel multiplexing. Background technique [0002] The proposal of multiple-input multiple-output (MIMO) technology has opened up a new field for modern wireless communication. It provides a future mobile communication system, especially for high-speed data access services, without increasing the bandwidth. It can greatly improve the means of system data rate and spectral efficiency. [0003] In the prior art, multiple antenna units are used at both the transmitting and receiving ends of a wireless system. Using the rich spatial multi-dimensional characteristics of the wireless scattering channel and working in a multi-input / multi-output mode, the system channel capacity can be improved dramatically. This is the ba...
