OFDM-CDM Performance Enhancement by Combining H-ARQ and Interference Cancellation [PDF]

, 2006
In this paper, superimposed packet allocation for orthogonal frequency-division multiple-access code-division multiplexing (OFDMA-CDM) is presented, where each transmitted packet is associated with one spreading code. An iterative algorithm which is

Non-linear echo cancellation - a Bayesian approach

, 2008
Echo cancellation literature is reviewed, then a Bayesian model is introduced and it is shown how how it can be used to model and fit nonlinear channels. An algorithm for cancellation of echo over a nonlinear channel is developed and tested.

Joint detection-estimation of directional channel parameters using the 2-D frequency domain SAGE algorithm with serial interference cancellation [PDF]

, 2002
In this paper, the serial interference cancellation (SIC) technique and the frequency domain SAGE (FD-SAGE) algorithm are jointly used to detect and estimate the radio channel parameters of interest.

Bootstrap Unit Root Tests [PDF]

We consider the bootstrap unit root tests based on autoregressive integrated models, with or without deterministic time trends. A general methodology is developed to approximate asymptotic distributions for the models driven by integrated time series ...

Decision Feedback Aided Bayesian Turbo Space-Time Equalizer for Parallel Interference Cancellation in SDMA Systems

, 2005
A novel Bayesian Decision-Feedback aided turbo Space-Time Equalizer (DF-STE) combined with a Parallel Interference Cancellation (PIC) scheme and designed for multiple antenna assisted receivers is introduced.

A multi-cycle fixed point square root module for FPGAs [PDF]

, 2012
This paper presents a module that solves the square root by obtaining a number of more significant bits from a look-up table as an approximate root. A set of possible roots are then appended and squared for comparison to the original radicand, finely ...

Identifying Sources of Business Cycle Fluctuations in Germany 1975–1998 [PDF]

In this paper, we estimate a small New Keynesian dynamic stochastic general equilibrium (DSGE) model for Germany for the period from 1975 to 1998 and use it to identify the structural shocks, which have driven the business cycle.
