Forward Error Correction (FEC) consumes excessive computation in a Software Defined Radio (SDR) system. In this work, a high-throughput flexible FEC processor is proposed for the decoding acceleration. The FEC processor enables Turbo/QC-LDPC/Convolutional Code decoding with software-hardware co-reconfigurability. A multi-algorithm unified trellis processing unit is introduced for resource sharing...
This paper presents a hardware accelerated NIOS-II implementation of a Turbo decoder. Firstly, a Matlab prototype consisting of a) an encoder made of a parallel concatenation of two RSC encoders and b) a decoder based on two identical SOVA decoders is constructed. Simulations of the prototype show that the BER decreases for every iteration in the decoder (down to 10-4), except for low SNR cases (below...
This work presents a field programmable gate array (FPGA) implementation of the min-sum iterative decoding algorithm for the (8,4) extended Hamming code using a reconfigurable computing system. The Mitrion-C high level language (HLL) is used to program the FPGAs, since it provides flexible tools for FPGA-based prototyping and functional verification for hardware design. A hardware-efficient implementation...
In this paper, we present a prototyping exercise, mapping a turbo decoder high-level description directly to FPGA for fast simulation of a software radio. The turbo decoder algorithm is described in C programming language and the mapping has been done directly using the high level synthesis tool CoDeveloper. The manual transformations made on the code to facilitate efficient compilation and to achieve...
