Turbo-equalization of Pulse Shaped Multi-carrier Modulation in Doubly Selective Channels
There is a growing demand for higher data rate systems that can function in a highly mobile environment. This mandates the design of communication systems that can function in doubly selective channels. Pulse-shaped multi-carrier modulation schemes prove to be an attractive option for transmission over doubly-dispersive channels. The pulse shapes are designed to yield an inter-symbol/inter-carr...
متن کاملTurbo Equalization/Estimation of Doubly Selective Channels using Basis Expansion and Tree Search
For turbo reception of coded transmissions over unknown doubly selective channels, such as time-varying ISI channels or frequency-varying ICI channels, we propose several soft noncoherent equalizers based on basis expansion (BE) channel modeling and tree-search, as a departure from traditional designs based on autoregressive (AR) channel modeling and/or trellis processing. By “noncoherent,” we ...
متن کاملBlock Transmissions over Doubly Selective Channels: Iterative Channel Estimation and Turbo Equalization
Modern wireless communication systems require high transmission rates, giving rise to frequency selectivity due to multipath propagation. In addition, high-mobility terminals and scatterers induce Doppler shifts that introduce time selectivity. Therefore, advanced techniques are needed to accurately model the timeand frequency-selective (i.e., doubly selective) channels and to counteract the re...
متن کاملEstimation and Direct Equalization of Doubly Selective Channels
We propose channel estimation and direct equalization techniques for transmission over doubly selective channels. The doubly selective channel is approximated using the basis expansion model (BEM). Linear and decision feedback equalizers implemented by time-varying finite impulse response (FIR) filtersmay then be used to equalize the doubly selective channel, where the time-varying FIR filters ...
متن کاملLow-complexity Serial Equalization of Doubly-selective Channels
In this paper, we propose a serial equalizer for doubly-selective channels. We use a Basis Expansion Model (BEM) Finite Impulse Response (FIR) to model the doubly-selective channel and to design the serial equalizer. In contrast to our previous works, we decrease the modeling error of the BEM FIR by fitting the BEM FIR to the true doubly-selective channel over a time-window that is independent ...
