Performance of Turbo-SISO, Turbo-SIMO, Turbo-MISO and Turbo-MIMO system using STBC
In this paper, performance of a Turbo coded wireless link is evaluated in the presence of Rayleigh fading for single-input single-output (SISO), single-input multipleoutput(SIMO), multiple-input single-output (MISO) and multiple-input multiple-output (MIMO) system. Turbo encoded and 64-ary Quadrature Amplitude Modulation (QAM) modulated data are further encoded using spacetime block coding (STB...
متن کاملComparative study of turbo equalization schemes using convolutional, convolutional turbo, and block-turbo codes
Turbo equalizers have been shown to be successful in mitigating the effects of inter-symbol interference introduced by partial response modems and by dispersive channels for code rates of 1 2. In this contribution, we comparatively studied the performance of a range of binary phase-shift keying turbo equalizers employing block-turbo codes, namely Bose–Chaudhuri–Hocquenghen turbo codes, convolut...
متن کاملTurbo Codes
The paper starts with a short overview of channel coding and the reader is reminded the concept of convolutional encoding. Bottlenecks of the traditional approach are described and the motivation behind turbo codes is explained. After examining the turbo codes design more in detail, reasons behind their efficiency are brought out. Finally, a real-world example of the turbo code used in the thir...
متن کاملComdined Turbo Block Decoding and Equalisation
In this paper, the combination of equalization and turbo decoding is studied. In the iterative decoding of a product code in block turbo coding system, the equalization process is performed within the iteration loop. The present study aims to investigate the decision feedback equalizer (DFE) incorporated in the iterative decoding. Simulation results show that the more severe the channel interfe...
متن کاملSeparate Turbo Code and Single Turbo Code Adaptive OFDM Transmissions
This paper discusses the application of adaptive modulation and adaptive rate turbo coding to orthogonal frequency-division multiplexing (OFDM), to increase throughput on the time and frequency selective channel. The adaptive turbo code scheme is based on a subband adaptive method, and compares two adaptive systems: a conventional approach where a separate turbo code is used for each subband, a...
