Iterative (Turbo Processing) Receiver Design of OFDM Systems in The Presence of Carrier Frequency Offset
In this paper, based on the principle of turbo processing, we propose two iterative receiver schemes for carrier frequency offset (CFO) compensation in orthogonal frequency division multiplexing (OFDM) systems. Our CFO compensation designs, one in time domain and the other in frequency domain, are based on joint estimation of time-varying channel and CFO. In our schemes, the random CFO problem,...
متن کاملMinimum intersymbol interference methods for time domain equalizer design
During initialization, discrete multitone receivers train a time domain equalizer (TEQ) to shorten the channel impulse response to a preset length, ν + 1. Arslan, Kiaei, and Evans report a Minimum Intersymbol Interference (Min-ISI) method for TEQ design. Min-ISI TEQs give the highest bit rates among single-FIR TEQs amenable to real-time implementation on programmable fixed-point digital signal ...
متن کاملReceiver Design for Single Carrier Equalization in Fading Domain
Single carrier frequency division multiple access (SCFDMA) is one well-known scheme, which has recently become a preferred choice for uplink channels. Due to the usage of single carrier, the performance of SC-FDMA systems degrades in deep frequency selective fading channels. In this paper, we propose a structure of equalizer based on frequency domain decision feedback which could be used for mu...
متن کاملADAPTIVE ITERATIVE LAYERED SPACE−FREQUENCY EQUALIZATION FOR SINGLE−CARREIR MIMO SYSTEMS (MonPmPO1)
We propose an adaptive iterative layered space−frequency equalization (AILSFE) structure for multiple−input multiple−output (MIMO) time−varying frequency selective channels, which incorporates iterative frequency−domain equalization (FDE) with hybrid interference cancellation. It is shown that AILSFE significantly outperforms the previously proposed LSFE with a modest increase of complexity, an...
متن کاملFrequency Domain DFE: System Design and Comparison with OFDM
A novel frequency domain equalizer for single carrier modulation is presented. It performs as a decision feedback equalizer (DFE) with the feedforward operating in the frequency domain, and a feedback filtering in time domain. The new scheme makes use of a data block transmission format which can be seen as a generalization of the zero padded transmission. Performance comparisons between FD-DFE...
