Research And Implementation Of Wide-band Multi-antenna Transmitter

With the rapid development of wireless communication technology in theseyears, and the increasing demands of the wireless communication system, MIMOtechnology is proposed. It can provide a good solution for the high demands of thecommunication system. It is a great breakthrough of the development of wirelesscommunication technology, and it has a great significance for wireless communicationsystem. The advantages of MIMO technology is that it can greatly improve thespectrum utilization of the communication system, and channel capacity underconditions that it does not increase the bandwidth of a communication system. Thispaper is based on wideband MIMO system transmitter, conducted on the transmitter RFfront-end research and design.First, this paper made a brief introduction of the paper background as well as thepaper structure.Secondly, this paper made a introduction of the performance index of thetransmitter in the wireless communication system, and described the basic principle ofthe transmitter, and introduces several of the more common transmitter structure, anddid a simple analysis of the performance of the different structures.Again, based on the specific indicators of the project requirements, we describedthe entire transceiver system design ideas. Based on the index requirements wedetermine the design project and select the device after analysis program. In hardwarecircuit, we introduce transmitter device and analysis its indicators, and complete systemschematic and PCB drawing.Finally, we introduce the test instruments and test environment of the entire system,then analysis the test result. And propose solutions for problem according to thedebugging process.
