Interconnect fabric technology such as RapidIO, InfiniBand and PCIe has evolved to 10Gbps. However, user applications still can't fully benefit from such high speed technology due to user-level protocols' high processing overhead and redundant data copies. It remains difficult to design and implement flexible and efficient communication software, especially in real-time applications. This paper introduces...
When signal-to-noise ratio (SNR) is low, the performance of unitary space-time modulation (USTM) is unsatisfactory. A novel scheme employing unitary space-time symbol-based turbo code (UST-SB-TC) can greatly reduce the time delay but its MAP decoding algorithm may cause the system instability. As we know, Log-MAP algorithm needs exponential processing and Max-Log-MAP would inevitably result in performance...
An intrinsic pitfall of unitary space-time modulation is that its performance is unsatisfactory at low signal-to-noise ratio. Concatenating it with turbo code is a possible solution, however, bit wise processing results in unacceptable calculation mount. A novel scheme employing unitary space-time symbol base turbo code can greatly reduce the time delay but its MAP decoding algorithm may lead to system...
