Problems solved by technology

However, due to the interference of multiple signals sent by multiple antennas in the MIMO system, and due to the influence of the channel environment, the signal-to-interference-noise ratio will be low when the channel environment is relatively poor, which limits the capacity improvement and Bit Error Rate Reduction

Abstract

The invention relates to the technical field of mobile communication, in particular to data sending technology for a multi-input multi-output (MIMO) system and corresponding data receiving technology. The embodiment of the invention provides a data sending method, a corresponding data receiving method, a corresponding data receiving device and corresponding data receiving equipment for the MIMO system, and is used for increasing the signal-to-interference-plus-noise ratio of received signals of the MIMO system and improving the performance of the system. The data sending method for the MIMO system comprises the following steps: at least two groups of data of the same user are subjected to channel coding and interweaving respectively, and interweaving patterns adopted when the data are interwoven are not same; two data sequences obtained after the interweaving are modulated respectively and then are sent, and interweaving pattern indication information adopted when the data are interwoven is sent.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and in particular to a data sending technology of a MIMO system and a corresponding data receiving technology. Background technique [0002] In recent years, multiple access technology, as one of the key technologies in mobile communication systems, has received widespread attention, which can realize multi-user communication at the same time and share limited wireless resources. Multiple access technologies are mainly divided into time division multiple access (Time Division Multiple Access, TDMA) technology, frequency division multiple access (Frequency Division Multiple Access, FDMA) technology and code division multiple access (Code Division Multiple Access, CDMA) technology. Orthogonal Frequency Division Multiplex Access (OFDMA, Orthogonal Frequency Division Multiplex Access, OFDMA) technology is based on frequency multiplexing, and is essentially an FDMA technology. O...
