Turbo-Like Coding for Spread-Spectrum Communications

A High-Speed Analog Turbo Decoder

A new type of iterative decoders based on analog computing networks, which are used to decode powerful error-correcting schemes, such as Turbo and Low-density parity-check (LDPC) codes, outperform their digital counterparts in terms of power consumption and speed. Only few analog Turbo decoders, all of them based on CMOS subthreshold technology have been implemented till now. This paper aims to...

High Speed Integrated Circuits for High Speed Coherent Optical Communications

High Speed Integrated Circuits for High Speed Coherent Optical Communications by Hyun-chul Park With the development of (sub) THz transistor technologies, high speed integrated circuits up to sub-THz frequencies are now feasible. These high speed and wide bandwidth ICs can improve the performance of optical components, coherent optical fiber communication, and imaging systems. In current optica...

Turbo Coded OFDM / QAM Scheme for a High - Speed Power Line Communication System

In this paper, performance of a turbo-coded OFDM system is analyzed and simulated in a power line communication channel. Since the power line communication system typically operates in a hostile environment, turbo code has been employed to enhance reliability of transmitted data. The performance is evaluated in terms of bit error probability. As turbo decoding algorithms, MAP (maximum a posteri...
