Rabbani Abolfazli, Ali Reza An Analog Decoder for Turbo-Structured Low-Density Parity-Check Codes. PhD thesis, Concordia University. In this work, we consider a class of structured regular LDPC codes, called Turbo-Structured LDPC TS-LDPC. TS-LDPC codes outperform random LDPC codes and have much lower error floor at high Signal-to-Noise Ratio SNR.
In this thesis, phd thesis on turbo codes, Min-Sum MS algorithms are adopted in the decoding of TS-LDPC codes due to their low complexity in the implementation. We show that the error performance of the MS-based TS-LDPC decoder is comparable with the Sum-Product SP based decoder and the error floor property of TS-LDPC codes is preserved.
The TS-LDPC decoding algorithms can be performed by analog or digital circuitry. Analog decoders are preferred in many communication systems due to their potential for higher speed, lower power dissipation and smaller chip area compared to their digital counterparts. In this work, implementation of the75 MS-based TS-LDPC analog decoder is considered. The decoder chip consists of an analog decoder heart, phd thesis on turbo codes, digital input and digital output blocks.
These digital blocks are required to deliver the received signal to the analog decoder heart and transfer the estimated codewords to the off-chip module. The analog decoder heart is an analog processor performing decoding on the Tanner graph of the code. Variable and check nodes are the main building blocks of analog decoder which are designed and evaluated. The check node is the most complicated unit in MS-based decoders. The minimizer circuit, the phd thesis on turbo codes block of a check node, is designed to have a good trade-off between speed and accuracy.
In addition, the structure of a high degree minimizer is proposed considering the accuracy, speed, power consumption and robustness against mismatch of the check node unit.
The measurement results demonstrate that the error performance of the chip is comparable with theory. It is shown that the proposed decoder outperforms the analog decoders that have been fabricated to date in the sense of error performance, throughput and energy efficiency.
This decoder is the first analog decoder that has ever been implemented in a sub nm technology and it improves the throughput phd thesis on turbo codes analog decoders by a factor of This decoder sets a new state-of-the-art in analog decoding.
