Abstract

Purpose

The purpose of this paper is to address the problem of polar quantization optimization. Particularly, the aim is to find the method for the optimal resolution‐constrained polar quantizer design.

Design/methodology/approach

The new iterative algorithm for determination of the optimal decision and representation magnitude levels and algorithm for optimization of number of phase cells within each magnitude level, is proposed.

Findings

At high rates, the new optimal polar quantizer outperforms the optimal polar compander for 0.2 dB, while the more significant gain should be expected at lower rates. In this paper, in order to enable practical implementation of quantizer model, algorithm which transforms real values for the optimal numbers of phase cells within magnitude levels into integer ones is also proposed. Moreover, the approximate closed form of signal‐to‐quantization ratio is derived.

Practical implications

Since circularly symmetric sources and complex presentation of signals arise in numerous applications, it can be concluded that the usage area of the suggested proposal is very wide (audio coding, image coding, spectral phase coding, synthetic aperture radars systems, coding of the discrete Fourier transform).

Originality/value

It should be emphasized that in contrast to earlier work, where models have been designed under high‐rate assumption, the obtained nonuniform unrestricted polar quantizer is optimal for all rates.

Abstract

Today tourism is recognised as a very complex social and economic phenomenon having a spatial, socio-cultural, economic, political, educational and environmental dimension. Furthermore, tourismis transformingtowards an individual and his/her needs, desires and interests, with a full respect for the surroundings and environment, which are given an increasing importance. Consequently, there have been changes not only in the structure of tourist consumption and in the behaviour of tourists, but also in the concept of a tourist offer. In this sense, numerous forms of special interest tourism are increasingly being developed in response to the needs of modern tourists to experience something new, authentic and different from their everyday environment. Tourists, saturated with the global trends' consequences that dominantly foster a kind of uniformity on their trips, are increasingly looking for the uniqueness or experience that is different from their own culture. Gastronomy, as a part of the local community's cultural identity, stood out as an authentic element of the tourist destination's offer, to which tourists are increasingly paying attention, which is increasingly becoming the basic motive of travelling for modern tourists.

Taking into account the current trends of the leading global source markets of the world, as well as the growing need to create a common tourist offer of the Western Balkan economies, this concept of Mountain Breakfast applied in the Western Serbia Region could represent a good example and a platform for connecting tradition, local producers, gastronomy and tourism.
