Present study focuses on identification and mapping of olive in the part of Roodbar region, Guilan, Iran, based on IRS images using spectral reflectance's stochastic and supervised classification techniques. Two methods evaluated to images controlled classification in order to separate olive orchards spectrum reflex from the other surface covers. At the first method, upper and lower limit of digital...
This study presents an exact analysis of circuit non-linearity and phase noise effects on orthogonal frequency division multiplexing (OFDM) communication systems. Using an analytical approach, the degradation effects of these impairments on the performance of OFDM systems are studied. A truncated power series is used to represent the third-order non-linear behaviour of a radio frequency circuit. The...
In this paper we develop analytical closed form expression for the capacity of a wireless ad hoc network. First, for the general case when nodes can adapt their communication rates to the link quality, a proper formulation for the total network capacity is presented based on the cumulative distribution function (CDF) of the signal to interference power ratio (SIR). Then, a closed form expression for...
In this paper, continuous phase modulation (CPM) is detected using TURBO-BLAST space-time architecture to improve the system performance. This is realized by implementing an iterative architecture according to the trellis structure of CPM modulation in space-time communication systems. This architecture provides the benefits of the space-time wireless communication systems while it preserves the advantages...
