Turbo space-time processing to improve wireless channel capacity
IEEE Transactions on Communications, 2000By deriving a generalized Shannon capacity formula for multiple-input, multiple-output Rayleigh fading channels, and by suggesting a layered space-time architecture concept that attains a tight lower bound on the capacity achievable. Foschini (see Wireless Pers.

MIMO iterative array processing with LMMSE turbo equalization
IEEE 60th Vehicular Technology Conference, 2004. VTC2004-Fall. 2004, 2005Multiple-input-multiple-output (MIMO) systems promise to provide significant increases in system capacity for future wireless communication systems. However, realization of the highest potential capacity of a MIMO system requires a high signal-to-noise ratio and, even more practically, any interference from other access points or other systems has to ...

Performance of simple turbo process with non-standard mapping
TENCON 2017 - 2017 IEEE Region 10 Conference, 2017This paper addresses a technique to further minimize error in wireless communication system. The proposed system uses non-standard mapping in Irregular Repetition Code (IRC) with Turbo processing and named as IRC_EM. The IRC_EM adopts a doped-accumulator as an improvement to obtain the Turbo Cliff.

Assessing the performance of turbo processing
2006This talk is dedicated to the turbo principle in digital communications. In order to understand how this principle was appeared, a brief historical review will be made since the beginning of the information theory field. Second, we will answer two fundamental questions about the turbo principle: "how and why does it work?".

Double Turbo Equalization of Continuous Phase Modulation with Frequency Domain Processing
IEEE Transactions on Communications, 2009In this paper, a doubly-iterative linear receiver, equipped with a soft-information aided frequency domain minimum mean-squared error (MMSE) equalizer, is proposed for the combined equalization and decoding of coded continuous phase modulation (CPM) signals over long multipath fading channels.

A Parallel Turbo Product Codes Decoder Based on Graphics Processing Units
2019 IEEE 21st International Conference on High Performance Computing and Communications; IEEE 17th International Conference on Smart City; IEEE 5th International Conference on Data Science and Systems (HPCC/SmartCity/DSS), 2019Turbo product codes (TPC) are a class of forward error correction (FEC) codes. They have good bit error rate (BER) performance at high code rate. It is relatively simple to implement the encoder of TPC and the decoding complexity of their decoder is reasonable. Therefore, TPC are widely used in various places such as satellite communication systems and

High-throughput decoding of block turbo codes on graphics processing units
2017 IEEE International Workshop on Signal Processing Systems (SiPS), 2017Block turbo codes (BTCs) can provide very powerful forward error correction (FEC) for several applications, such as optical networks and NAND flash memory devices. These applications require soft-decision FEC codes to guarantee the bit error rate (BER) of under 10−12 which is, however, very difficult to verify with a CPU simulator.
