Embodiment Construction

[0030] The present invention utilizes the statistical independence of transmission signals in time in mobile communication systems and the statistical independence in frequency domain in broadband multipath delay communication systems, and combines Alamouti format, orthogonal transformation and interleaving technology to propose There are space-time block coding formats with 2 transmit antennas at the end, and 1 or more receive antennas at the receive end. For the sake of brevity, the description of the present invention takes one receiving antenna as an example, and the encoding and decoding formats of more than one receiving antenna can be easily obtained.

[0031] Taking the 2nd-order orthogonal transformation as an example, the transmission structure of the present invention is as follows figure 1 As shown, the complex signal from the modulation mapping is first divided into two groups of signals, and then each group of signals is subjected to 2×2 orthogonal transformatio...

Abstract

This invention discloses an empty time code transmission method for a multi-antenna communication system including: dividing multiple signals from the modulation image into multiple signal groups to be ingaged in orthogonal transformation then interleaving process, the Alamouti formate is used to transmit two sets of processed signals.

Description

technical field [0001] The present invention relates to the technical field of multi-antenna transmission and reception (MIMO) communication, specifically, the present invention mainly relates to a space-time code transmission and decoding reception method in a communication system with two transmission antennas. Background technique [0002] MIMO technology is considered to be one of the major advances in modern communication technology. MIMO technology can be simply defined as multiple antennas are equipped at both the transmitting end and the receiving end of the communication system. The key point is to use the independent multipath transmission fading between each antenna to improve the capacity and (or) reliability of the communication system. The multipath transmission fading is traditionally considered to be harmful to the communication system. [0003] There is multi-path fading in the signal transmission in the mobile communication system, and the energy of the re...
