| Summary: | 碩士 === 國立臺北科技大學 === 電腦與通訊研究所 === 99 === For non-relaying scheme, the previous work proposed a distributed space-time block code (DTBC) considering information exchange errors in two-user cooperative systems. We propose a distributed Hybrid MIMO Transceiver scheme (HMT) considering information exchange errors in three-user cooperative systems. For relaying scheme, the previous work also proposed an un-coded demodulated and forward relay and considering demodulation errors in the relay in two-user cooperative systems. We propose the relay-assisted distributed HMT scheme considering information exchange errors in 3-user cooperative systems, the differences are that our scheme has 3x2 HMT with transmit antenna selection in source-to-relay, source-to-destination, and relay-to-destination links, but the previous scheme has the 2x2 un-coded scheme in these three links. For both non-relaying and relaying scenarios, the simulation results show the proposed schemes have lower bit error rate (BER) than the previous schemes at the same 4 bits/sec/Hz transmission rate.
