Quantization

Scalar field systems containing higher derivatives are studied and quantized by Hamiltonian path integral formalism. A new point to previous quantization methods is that field functions and their time derivatives are considered as independent canonical variables. Consequently, generating functional, explicit expressions of propagators and Feynman diagrams in φ3 theory are found.

This paper deals with enhancing the error resilient of the Switched Split Vector Quantization (SSVQ) techniques by adopting the optimal Index Assignment approach, a Joint Source-Channel coding method. SSVQ is one of the latest structured vector quantization schemes and it has several advantages over other schemes.

This paper considers a two-hop two-way relay system which uses the Alamouti space-time code for signaling between all nodes and channel quantization for PNC mapping at the relay. Specifically, based on the concept of CQ-PNC we derive a PNC mapping rule for two pairs of network coded symbols.

This work addresses the problem of feature indexing to significantly accelerate the matching process which is commonly known as a cumbersome task in many computer vision applications. To this aim, we propose to perform product sub-vector quantization (PSVQ) to create finer representation of underlying data while still maintaining reasonable memory allocation.

The main goal of the thesis is to develop a signal processing which exploits the benefits of iterative decoding for MIMO receivers of next generation of mobile TV standard, DVB-NGH but moreover significantly reduces the receiver complexity. The signal processing is based on MMSE equalization with a priori inputs and quantized log-likelihood ratios.

In this paper we use the method of the second quantization to investigate possibility of superfluidity formation in the asymmetric nuclear matter. Using quasi-spin formalism to study the problem of deuteron condensation and applying the Hatree - Fock - Bogoliubov approximation to investigate the exceeding neutron system in the deuteron condensation.

We present an analysis of bounded-energy low-tension maps between 2-spheres. By deriving sharp estimates for the ratio of length scales on which bubbles of opposite orientation develop, we show that we can establish a ‘quantization estimate’ which constrains the energy of the map to lie near to a discrete energy spectrum. One application is to the asymptotics of the harmonic map flow; we find uniform exponential convergence in time, in the case under consideration.
