BER analysis of a set of TCM schemes for reducing cochannel interference in cellular mobile communication
(2000)
Scarcity of the frequency band is acting as a bottleneck to the tremendous advancement in the field of mobile communication. Nowadays cellular technology is being invariably employed in mobile communication to maximize the ...
Synthesis of FIR lattice structures
(2000)
The usual procedure for synthesising the Nth order digital FIR transfer function AN(z) in which the constant term is unity and the coefficient of z-N is -aN(N) by a lattice structure fails if aN(N)=±1. The author is concerned ...
A 3.3 V compatible 2.5 V TTL-to-CMOS bidirectional I/O buffer
(2000)
Design of a 3.3 V compatible 2.5 V TTL-to-CMOS bidirectional I/O buffer is proposed. Gate oxide protection was implemented without active voltage degradation, which reduces static and dynamic current levels and improves ...
Performance of predetection dual diversity in correlated Rayleigh fading: EGC and SD
(2000)
Using a series approach, expressions for the average symbol error probability (SEP) of coherent binary signals over a correlated Rayleigh fading channel with dual predetection equal gain combining (EGC) and selection ...
Indexing for local appearance-based recognition of planar objects
(2002)
Local appearance-based approaches for planar object recognition do not support efficient means for indexing of object models. The size of the feature set which needs to be stored and processed is also large. To reduce ...
Digital implementation of an advanced static compensator for voltage profile improvement, power-factor correction and balancing of unbalanced reactive loads
(2000)
In this paper, a three-phase advanced static compensator (STATCOM) is proposed to compensate reactive power either for regulating ac supply voltage at a constant value or for unity power-factor and balancing of unbalanced ...
Performance evaluation of PIN+OA and APD receivers in multi-wavelength CDMA and WaCDMA networks
(2001)
In this paper, the performance of multi-wavelength optical orthogonal code division multiple access (MWOCDMA) communication network and hybrid wavelength code division multiple access (WaCDMA) network are investigated. In ...
Reconstruction based recognition of scenes with multiple repeated components
(2001)
This paper proposes an invariance based recognition scheme for scenes with multiple
repeated components. The scheme considers three component subsets which characterize the scene completely. Each such three component subset ...
An efficient approach for voltage security analysis and enhancement
(2000)
This paper presents an efficient one step look-ahead approach for post-contingency loadability limit analysis and its enhancement in critical cases. This is achieved by using steady state analysis tool judiciously within ...
Vector quantization of excitation gains in speech coding
(2000)
In this paper, we consider vector quantization of excitation gains in code-excited linear predictive (CELP) speech coder using the average error in reconstruction of the excitation signal as the distortion measure and use ...
