Abstract

The invention relates to a method and device for realizing the coding and decoding of full speed transmission in an MIMO system; wherein, a transmitter respectively adopts m coding modes to carry out coding on m signals to be coded (m refers to an integer more than 1) to obtain m coding signals; the coded signals are respectively transmitted by m transmitting antennas in the same timeslot so as to realize the transmission of full speed. The invention provides a special coding method in particular. The coding method can be adopted to carry out coding on the signals to be coded, thus not only being able to realize the transmission of full speed, but also being able to improve the reliability of data transmission without increasing the coding time delay and the coding complexity.

Description

technical field

[0001] The present invention relates to a MIMO communication system, in particular to a method and device for encoding and decoding in the MIMO system. Background technique

[0002] Multiple-input multiple-output (MIMO) technology is a major breakthrough in the field of wireless communication, and it is one of the key technologies that must be adopted in the new generation of mobile communication systems. This technology can double the capacity and capacity of the communication system without increasing the bandwidth. Spectrum utilization.

[0003] There are two main design goals of the existing MIMO technology: one is to obtain higher anti-fading performance by utilizing space diversity, and the other is to obtain high-rate data transmission by increasing the capacity of the MIMO fading channel. For example, space-time orthogonal codes and space-time trellis codes belong to the performance-oriented class coding for the first goal; Rate-oriented class codin...
