Embodiment Construction

[0022] In the embodiment of the present invention, the relay device processes the LDC-encoded signal according to the configured codeword row component identifier, obtains the codeword row component signal and sends it, and realizes a virtual MIMO system composed of relay devices. Each relay device One code word line component signal is sent, and multiple code word line component signals are combined in space, realizing space-time diversity transmission and improving transmission performance. And because the LDC coding is realized in the virtual MIMO system, the configuration flexibility is improved.

[0023] see figure 1 , the main method flow of space-time diversity transmission in this embodiment is as follows:

[0024] Step 101: The relay device obtains the LDC encoded signal.

[0025] Step 102: The relay device processes the LDC-encoded signal according to the configured codeword row component identifier to obtain a codeword row component signal.

[0026] Step 103: The...

Abstract

The invention discloses a method for space-time diversity transmission, which is used for realizing space-time diversity transmission in a relay system to increase transmission performance and configuration flexibility. The method comprises the following steps that: a relay device acquires an LDC (Linear Dispersion Code) coded signal; the relay device processes the LDC coded signal according to configured code word line component identification to obtain a code word line component signal; and the relay device sends the code word line component signal. The invention also discloses a device used for realizing the method.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for space-time diversity transmission. Background technique [0002] With the development of communication technology, in order to improve the reliability and transmission rate of the communication system, multiple input multiple output (Multiple Input Multiple Output, MIMO) technology is proposed in the industry, which can greatly improve the reliability and rate of communication. At present, multi-antenna transmission and reception have been realized on the base station. However, user equipment and relay equipment are limited by volume, power consumption, and technology, making it difficult to install multiple antennas on them. This greatly limits the application of the MIMO technology. In order to solve this problem, some scholars have proposed a technology called cooperative diversity in recent years. This technology can enable terminals to share each other’s a...
