Ant Colony Algorithm for Non Constraint Optimization Problem

Abstract The key of developing high frequency wideband communication system is how to model the HF wideband channel. Some HF wideband models are discussed and compared in this paper, including Vogler model, parallel subband model, two improved Watterson models and Pseudo- Deterministic model. As a deterministic model, Volger model basically describes the characteristics of HF wideband channel, but it also needs to be improved. The improvement of Vogler model is given in this paper.
