Embodiment Construction

[0047] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

[0048] As shown in Figure 2, it is a schematic diagram of the main process of the present invention, the scheme has M transmitting antennas at the transmitting end, as seen from Figure 2, mainly includes the following steps:

[0049] S100. The transmitting end of the MIMO system has M transmitting antennas, and selects K transmitting antennas among them to transmit K transmission signals.

[0050] Optionally, assuming that the MIMO system is a closed-loop system (but the present invention is not limited thereto), the receiving end feeds back the transmitting antenna usage information to the transmitting end, indicating that the next TTI can be spatially multiplexed and simultaneously transmitted in parallel by different channels The number K of transmitted signals, said K

Abstract

The invention discloses a method and system of emission signal in multi antenna communication. The method includes: A. MIMO system emission end possesses M emission antenna to emit k ways of emission signal; B. every symbol period of TTI of the emission end adopts K emission antenna and adopts space multiplexing and emits K ways of emission signal, one or more of remained M-K emission antenna is used to emit signal. When number of emission antenna is less than max number of useable emission antenna in single code mode, the remained emission antenna is used to time space block code to obtain diversity plus. The invention also provides a method of HAR cause of multi codes communication scheme in MIMO system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a multi-antenna communication method and system. Background technique [0002] Multiple-Input Multiple-Output (MIMO, Multi-Input Multi-Output) technology refers to using multiple transmitting antennas and receiving antennas at the transmitting end and receiving end respectively, and signals are transmitted and received through multiple antennas at the transmitting end and receiving end, thereby improving each Quality of service (bit error rate or data rate) for each user. The traditional communication system is a single-input single-output (Single-Input Single-Output, SISO) system. Multiple-Input Single-Output (MISO) and Single-Input Multiple-Output (Single-Input Multiple-Output, SIMO) based on transmit diversity and receive diversity are also part of MIMO. [0003] Currently in MIMO technology, Alamouti space-time block code is used to transmit signals to obtain diversity gai...
