Multi-antenna transmission system and method

Abstract

The invention discloses a multi-antenna transmission system and a multi-antenna transmission method. A transmitter of the system comprises a spatial modulation module, a single-carrier modulation module, a cyclic prefix insertion module, a digital/analogue (D/A) conversion module and a first radio frequency link module. The system is characterized in that: the transmitter also comprises a data distribution module and a first antenna selection module. According to the method, an information bit stream to be transmitted is divided into two paths through data distribution, wherein one path comprises information for controlling serial numbers of antennae, and is directly transmitted to an antenna selection module, and the other path comprises data information bits which are modulated, subjected to radio frequency processing and then transmitted to the antenna selection module; and then an antenna is selected to transmit information. Therefore, compared with the conventional method, the method has the advantages that: the number of radio frequency links is decreased; and system cost is decreased.

AI Technical Summary

Benefits of technology

This technology allows multiple radios (transmitting) devices within range to communicate wirelessly without having them all working together at once - instead relying on one device's own communication capabilities. It divides up each piece of information that needs to travel across different paths before reaching its destination where it can use this divided signal. By doing things like transmitting signals over separate wires or wireless networks, fewer radiofrequency chains are needed while still maintaining their effectiveness.

Problems solved by technology

This patented describes how spatial modulated techniques help improve wireless networks' performance without requiring more expensive equipment than what was previously possible due to their limitations on communicating resource allocation. These improvements include improved signal quality at different frequencies for better reception even with fewer receivers while also reducing costs associated with longer connections between devices.
