A multiplicative cancellation approach to multipath suppression in FM Radio
Moir, T; Pettigrew, AM (Springer, 2014)The deceptively simple problem of a single inverted reflection in ordinary frequency modulated (FM) radio is considered. It will be shown that this problem has been overlooked in the literature and causes major breakdown ... -
Adaptive crosstalk-resistant noise-cancellation using Kalman filters
Moir, T (The Institute of Mathematics and its Applications (IMA), 2012)A crosstalk-resistant method of noise-cancellation is used to separate a mixture of two non-stationary signals.(eg speech). Whereas this idea has been used previously using least-mean squares (LMS) in a cross-coupling mode, ... -
Blind source separation for adaptive speech control
Moir, T; Alam, F; Harris, J (AUT University, 2011)Crosstalk resistant adaptive noise cancellation (CTRANC) is a method of separat-ing convolutively mixed sources where little a priori information is known about the system. Possible areas of application for such an algorithm ... -
Filtering, smoothing, and prediction using a control-loop spectral factorization method for coloured noise
Moir, T (John Wiley & Sons, 2012)A method for the linear least-squares estimation of random signals contaminated with random noise is shown that uses a new method of spectral factorization. It is shown that the optimal filter can be written entirely in ... -
Improving Persian-English statistical machine translation: experiments in domain adaption
Mohaghegh, M; Sarrafzadeh, A; Moir, T (CiteSeerX, 2011)This paper documents recent work carried out for PeEn-SMT, our Statistical Machine Translation system for translation between the English-Persian language pair. We give details of our previous SMT system, and present our ... -
Inverting non-minimum phase FIR transfer functions
Moir, T (Scentific and Academic Publishing, 2013)The approximate solution to the inverse of a non-minimum phase finite-impulse response (FIR) transfer function is given. Such a problem arises in many areas which include room-acoustics and channel equalisation. Unlike ... -
Knowing the wheat from the weeds in noisy speech
Moir, T; Agaiby, H (International Speech Communication Association (ISCA), 1997)This paper introduces a word boundary detection algorithm that works in a variety of noise conditions including what is commonly called the 'cocktail party' situation. The algorithm uses the direction of the signal as the ... -
Polynomial Wiener LQG Controllers Based on Toeplitz Matrices
Moir, T (Institute of Physics (IoP), 2022)This paper re-examines the discrete-time Linear Quadratic Gaussian (LQG) regulator problem. The normal approach to this problem is to use a Kalman filter state estimator and Kalman control state feedback. Though quite ... -
Trying-out Digital Technologies in Trying Times: A Collection of Observations From a Collegial Adventure During Covid-19
Hooper, P; Anderson, T; Nates, R; Moir, T; Beckerleg, M; Protheroe, M; Whittington, C; Hadrup, M (Australasian Association for Engineering Education (AAEE), 2020)CONTEXT In recent decades there has been significant discussion in the popular press about digital technologies enabling society to transition to a working-from-home scenario. Similarly, literature in the engineering ...
