High Speed Decoding for High-Rate and Short-Length Reed–Muller Code Using Auto-Decoder
نویسندگان
چکیده
In this paper, we show that applying a machine learning technique called auto-decoder (AD) to high-rate and short length Reed–Muller (RM) decoding enables it achieve maximum likelihood (MLD) performance faster speed than when fast Hadamard transform (FHT) is applied in additive white Gaussian noise (AWGN) channels. The approximately 1.8 times 125 the FHT for R(1,4) R(2,4), respectively. number of nodes hidden layer AD larger input layer, unlike conventional auto-encoder (AE). Two ADs are combined parallel merged together, then cascaded one fully connected improve bit error rate (BER) code.

High Speed Viterbi Decoder Design With A Rate Of 1⁄2 Convolution Code For Tcm Systems
High speed Viterbi decoder design for trellis coded modulation (TCM) is presented in this paper. It is well known that the Viterbi decoder (VD) is the dominant module for determining shortest path. We propose a pre-computation architecture incorporated with T-algorithm for VD, which can find the shortest path without degrading the decoding speed much. A general solution to derive the optimal pr...
متن کاملHigh-Speed Decoding of the Binary Golay Code
Recently, some table-lookup decoding algorithms (TLDAs) have been used to correct the binary Golay code. This paper proposes an efficient high-speed TLDA called message-syndrome decoding algorithm (MSDA) by using the message syndrome to correct the binary systematic Golay code. The proposed MSDA is based on the novel message-syndrome lookup table (MSLT). The MSLT merely consists of 12 candidate...

In this paper a new phase-frequency detector is proposed using transmission gates which can detect phase difference less than 500ps. In other word, the proposed Phase-frequency Detector (PFD) can work in frequencies higher than 1.7 GHz, whereas a conventional PFD operates at frequencies less than 1.1 GHz. This new architecture is designed in TSMC 0.13um CMOS Technology. Also, the proposed PFD a...
