VLSI implementation for a 4times4 multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) transceiver is described that targets 1-Gbps data transmission for next-generation wireless LAN systems. The IEEE802.11 Very High Throughput (VHT) Study Group concluded that a signal bandwidth of more than 80 MHz is needed to achieve 1-Gbps throughput in the MAC layer. The proposed...
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 reduces complexity. We evaluate the communication...
