| Summary: | 碩士 === 淡江大學 === 電機工程學系碩士班 === 98 === With the development of multiple-input and multiple-output (MIMO) communication system it still has the problem of implement multi-antenna system on the mobile set it is due to the limited space available on the mobile set. In the Modulated Scattering Antenna Array (MSAA) system at the receiver side it consists of one normal antenna and several modulated scattering elements (MSEs) withonly one RF circuit is fabricated to attain the MIMO advantages.
In this study we consider an MIMO communication system based on space-time code (STC). In this system it is implemented with four transmitter antenna which have the normal antenna architecture while at the receiver side it is implemented withtwo regular antenna and two auxiliary antennas thatare designed based on the concept of the MSAA technique without any feasible RF circuits implemented. The characteristics and performance of system are studied extensively when the carrier frequencies at the auxiliary antenna are fixed or ‘scanning’. Various diversities based on coding techniques and/or modulating methods are also considered in the system performance evaluation. It reveals that with this auxiliary antenna design at the receiver side it can attain the advantages of MIMO system while reducing the required antenna space and eliminating the complexities of RF circuits design.
