Improved Receivers for Digital High Frequency Waveforms Using Turbo Equalization

چکیده
We develop a Turbo equalization-based receiver for serial-tone HF waveforms, where the conventional decision feedback equalizer is replaced by a soft-in soft-out (SISO) equalizer, and the receiver iterates soft information between the equalizer and the decoder. To keep the computational burden of the iterative equalization and decoding procedure as low as possible, the SISO equalizer is designed using a linear filter perfoming soft inter-symbol interference cancellation. Simulation results show that the proposed receiver performs about 2 dB signal-to-noise ratio better than a conventional DFE-based receiver.

Improved Receivers for Digital High Frequency Communications: Iterative Channel Estimation, Equalization, and Decoding (Adaptive Turbo Equalization)
We address the problem of improving the throughput and the availability of digital communications in the High Frequency (HF, 3-30 MHz) band. In standardized military waveforms, the data is protected by an error-correcting code (ECC), and the code bits are shuffled by an interleaver and mapped onto a signal constellation for modulation onto a single carrier. Training sequences are multiplexed in...
متن کاملTurbo-equalization for bandwidth-efficient digital communications over frequency-selective channels
This thesis deals with the problem of combining equalization with decoding for high data ratebandwidth-efficient transmissions over frequency-selective channels. Specifically, we focus on Turbo-Equalization which establishes an exchange of soft information between the equalizer and the decoderin an iterative manner. We first consider MAP turbo-equalizers which rely on trellis-based ...

For evolution of the GSM/EDGE radio access network (RAN), the use of higher order modulation like 16and 32-ary quadrature amplitude modulation (QAM) is considered in standardization for increased peak data rates and reduced transmission delays. In this paper, an optimized receiver design for different packet data transmission schemes is proposed. Turbo coding and turbo equalization is discussed...

This paper presents a general structure for Minimum Mean Square Error (MMSE) equalizers from which we can derive instances such as the: two proposed Linear Equalizers with Extrinsic Feedback (LE-EF), Linear Equalizer (LE) and Decision Feedback Equalizer (DFE). The Extrinsic Information Transfer (EXIT) chart was used to analyze the two proposed MMSE LE-EF receivers and their characteristics was ...
متن کاملTurbo Equalization for DS-CDMA with Frequency-domain Equalization
Abstract In direct sequence code division multiple access (DS-CDMA), frequency-domain equalization (FDE) based on minimum mean square error (MMSE) criterion can be applied to exploit the channel frequency-selectivity and therefore can replace the conventional rake combining with much improved bit error rate (BER) performance. However, the residual inter-chip interference (ICI) is present after ...
