The adaptive step-size (AS) code-constrained minimum output energy (CMOE) receiver for nonstationary code-division multiple access (CDMA) channels is proposed. The AS-CMOE algorithm adaptively varies the step-size in order to minimise the CMOE criterion. Admissibility of the proposed method is confirmed via the reformulation of the CMOE criterion as an(More)
Identification of good metaphase spreads is an important step in chromosome analysis for identifying individuals with genetic disorders. The process of finding suitable metaphase chromosomes for accurate clinical analysis is, however, very time consuming since they are selected manually. The selection of suitable metaphase chromosome spreads thus represents(More)
—In this paper, a low complexity adaptive step-size filtered gradient-based scheme for per-tone equalisation is investigated for discrete multitone systems. A variant of the filtered gradient adaptive algorithms has been presented in literature for the normalised version of the orthogonal gradient adaptive algorithm which employs the mixed-tone(More)
Recommended by Azzedine Zerguine We present a bit rate maximising per-tone equalisation (BM-PTEQ) cost function that is based on an exact subchannel SNR as a function of per-tone equaliser in discrete multitone (DMT) systems. We then introduce the proposed BM-PTEQ criterion whose derivation for solution is shown to inherit from the methodology of the(More)
This paper presents a conjugate gradient minimum output energy (CG-MOE) algorithm for frequency domain MC-CDMA receivers. The CG-MOE algorithm employs the basis of the conjugate gradient (CG) and minimum output energy (MOE) algorithms. The CG-MOE algorithm does not require training signal yet robust to the near-far problems. The CG-MOE has a comparable(More)
We explore an approach for complexity reduction for fault diagnosis problems. The underlying algorithm is a sequential Monte Carlo method known as the Rao-Blackwellised Particle Filter or RBPF. In this paper, we show that the complexity of the RBPF algorithm can be reduced by applying the Kalman updating step to only one representative particle of a group(More)
In this paper, a time-reversal based space-time block code (TR-STBC) downlink multi-carrier code division multiple access (MC-CDMA) scheme for multiple-input multiple-output (MIMO) array antenna is presented. A TR space-time chip semiblind multiuser receiver with mixing parameterisation is proposed. The TR space-time shifted receive signal matrix using the(More)
