Abstract: This paper proposes an efficient implementation of turbo decoder used in joint detection and decoding receiver. The work is based on high speed wireless packet transmission system. The turbo ...

This paper propose an improved method called the modified warm-up-free parallel window(PW) MAP decoding schemes to implement highly-parallel Turbo decoder architecture based on the QPP(Quadratic ...

TC7000-LTE is a convolutional turbo code (CTC) decoder optimized for FPGAs. Its unique pipe-line architecture enables to reach very high clock frequencies on high end FPGAs It offers several ...

This article focuses on techniques to decode UMTS Turbo codes efficiently using a general purpose DSP processor with MAP (maximum a posterior) decoding algorithm. Since MAP decoding is costly both in ...

For the well-known 3G mobile communications standard UMTS, four different service classes have been specified. Considering two turbo decoding algorithms, like SOVA and log-MAP, it would be desirable ...

Abstract: We model the density of extrinsic information in iterative turbo decoders by Gaussian density functions. This model is verified by experimental measurements. We consider evolution of these ...

This paper deals with the presentation of different multi-user detectors in the Universal Mobile Telecommunications System (UMTS) context. The challenge is always to optimize the compromise between ...

A neural network-based decoder, based on a long short-term memory (LSTM) network, is proposed to solve the problem of high decoding delay caused by the poor parallelism of existing decoding algorithms ...

Lucent Technologies said Tuesday that it's ready to license new cell phone technology it says will let carriers build telephone networks that are 10 times faster than anything now commercially ...

Communication-system designers have always had to deal with trade-offs among data reliability, efficient use of available spectrum, data throughput, and cost. Error-correction coding (ECC) is one of ...
