time reversal (tir) technique is an effective and simple method for data transmission in extremely multipath indoor uwb channels that mitigates the complexity of receiver by its own time focusing feature. although, tir method has the suitable performance, but it is sensitive to the non-ideal channel estimation error. in this paper at first, the bit error probability of tir-uwb communication sys...

due to the tilt of the platform carrying the synthetic aperture radar(sar), the image formation algorithms(like rda) can not yield to good quality images from the ground. therefore, it is convenient to use a two-step approach for motion compensation in image formation algorithms. in this paper, using an approximated linear model for the motion error and the impact of range compression step of r...

This paper presents the design of a new error compensation model for providing QoS support on a wireless network. The compensation model uses different compensation strategies for the different priority classes in conjunction with a Multiclass Priority Fair Queuing (MPFQ) algorithm. Criteria for fair error compensation and a classification of error compensation models are established in order t...
