This work presents a hybrid of the minimum mean square error (MMSE) multiuser detection (MUD) and successive interference cancellation (SIC) in conjunction with an information reuse scheme for direct-sequence code division multiple access (DS/CDMA) systems. The hybrid MUD first divides the users into groups with each group consisting of users with a close(More)
In this paper, we address a one-dimensional (1-D) estimation of signal parameter via rotational invariance technique (ESPRIT)-based algorithm, referred to as the SPS-ESPRIT, to jointly estimate the directions of arrival (DOAs) and polarization of the incoming plane waves with a co-centered orthogonal loop and dipole (COLD) array. The proposed algorithm(More)
Abstract: A new electronically tunable mixed-mode biquadratic filter with three current controlled current conveyor transconductance amplifiers (CCCCTAs) and two grounded capacitors is proposed. With current input, the filter can realise lowpass (LP), bandpass (BP), highpass (HP), bandstop (BS) and allpass (AP) responses in current mode and LP, BP and HP(More)
This paper presents a generalized sidelobe canceller (GSC)-based adaptive beam- former, in which the signals passing through the lower branch of the GSC are separated into different layers of subspaces. With such a hierarchical subspace decomposition, the computational overhead required by the beamformer can be reduced and the convergence rate in adaptive(More)
This paper presents a subband beamformer with the generalized sidelobe canceller (GSC) as the underlying structure. The approach determines the statistical optimum filter banks succeeding the band coefficients based on the minimum mean-square error criterion. As a consequence, the signals passing through the lower branch of the GSC is decomposed into more(More)
This paper presents a decision feedback subband generalized sidelobe canceller (GSC), in which the design of the statistically optimum filter bank decomposition of the signals passing through the lower branch of the GSC as well as the signal after the decision feedback based on the minimum mean-square error criterion is addressed. The new beamformer not(More)

In this study, an electronically tunable resistorless dual-mode quadrature sinusoidal oscillator, based on current controlled current conveyor transconductance amplifier (CCCCTA) and two grounded capacitors is presented. The proposed resistorless oscillator employs a single CCCCTA and two grounded capacitors and thus is well suited for integrated circuit(More)
