This paper focuses on the study of low density parity check (LDPC) coded multiple-input multiple-output (MIMO) systems for high throughput wireless communication. The evaluation and implementation of quasi-cyclic LDPC (QC- LDPC) code in MIMO-OFDM systems are presented. QC-LDPC has comparative error correcting performance with random LDPC and considerably(More)
In this paper, the evaluation and the implementation of quasi-cyclic LDPC (QC-LDPC) codes in MIMO-OFDM systems are presented. QC-LDPC has comparative error correcting performance with random irregular LDPC and considerably reduces complexity. We evaluate communication performance of the QC-LDPC coded system based on the IEEE802.11n standard in a 4 times 4(More)
Keywords: Shallow water flow Velocity measurement Electrolyte tracer Virtual boundary condition Sensitivity analysis s u m m a r y Accurate measurement of hill-slope shallow water flow velocity is an important issue in soil erosion prediction. The pulse model of electrolyte tracer advanced by Lei et al. (2005) indicated that the boundary condition is(More)
—The multiple-input multiple-output (MIMO) technique can greatly improve coverage and throughput in wireless networks. However, varying channel parameters create unfavorable conditions that make the transmission less reliable. Unfortunately, many previous MIMO evaluations suffer from limited practical relevance due overly-simplified assumption about the(More)
