Polar codes are proven capacity-achieving and are shown to have equivalent or even better finite length performance than turbo/LDPC codes under some improved decoding algorithm over the Additive White Gaussian Noise (AWGN) channels. Polar coding is based on the so-called channel polarization phenomenon induced by a transform over the underlying binary-input channel. The channel polarization is found...
Expectations and requirements for wireless communication systems continue to grow rapidly. Reliability is one of the most challenging criterions. Soft combined turbo codes technique aims to improve the error correction capability of turbo codes by using soft combining principle, at bit level, inside the turbo decoder. In particular, this approach is based on weight factors which are key elements that...
In this paper we propose a low-complexity and high performance sum-of-sinusoid based architecture for the accurate simulation of Mobile-to-Mobile Rayleigh fading channels. Presented contributions concern the issues of designing and implementing a “double ring” Mobile-to-Mobile emulator, based on the Random Walk Process to reproduce accurately the behavior of the considered channel. Implementation...
A low-complexity and high performance configurable Double Rayleigh Mobile-to-Mobile fading channel emulator is proposed as well as its High Level Synthesis. The design and implementation of the proposed architecture based on a variant of the white Gaussian noise filtering method uses a minor hardware resource. The designed system is modeled using C/C++ high level language. Then the synthesis task...
