Wireless technology in industrial environments is considered due to potential for saving in cable cost, high flexibility in factories, tracing the products and increasing optimization of process. Optimized use of wireless technology advantages is not possible without exact recognition of channel. Thus, this paper presents an exact model to describe ultra wide band channels (UWB) based on channel impulse response based on Saleh-Valenzuelain industrial environments by a new cluster identification algorithm. In the model, multi-path interference, fading and frequency and time dispersion effects were considered to increase accuracy and practicality of model. Two different approaches are considered for validation of proposed algorithm. In the first approach, propagation channel IEEE802.15.4a is simulated in Matlab environment and is identified by relevant algorithm. In the second approach, by real data of measure impulse response of channel, algorithm efficiency is evaluated. Both mentioned approaches showed strong performance of proposed algorithm in estimation and identification of channel in industrial environment.
