Fast and Area-Efficient Sphere Decoding Using Look-Ahead Search
— Sphere decoding enables maximum likelihood (ML) detection with fairly low complexity in the MIMO wireless systems, but it takes hundreds cycles at low SNR environment. This pap...

Application of Nonbinary LDPC Codes for Communication over Fading Channels Using Higher Order Modulations
Abstract— In this paper, we investigate the application of nonbinary low density parity check (LDPC) codes over Galois field GF(q) for both single-input single-output (SISO) and...

Infinity-Norm Sphere-Decoding
Abstract--Promising approaches for efficient detection in multiple-input multiple-output (MIMO) wireless systems are based on sphere-decoding (SD). The conventional (and optimum) n...

Iterative Correction of Clipped and Filtered Spatially Multiplexed OFDM Signals
— Peak-to-Average Power Ratio (PAPR) reduction in multicarrier systems with multiple transmit and receive antennas is considered. One attractive method for reducing the PAPR is t...
