The problem of sampling in data acquisition systems is considered in this paper. It is shown, that spectrum formation with desirable amplitudes in given spectral areas is possible if signal samples are presented as compound samples of special form. The technique of compound sample formation is offered. The approach makes it possible to exclude modulator and demodulator from data acquisition system...
This paper is aimed to show the efficiency of downlink control channel (PDCCH — Physical Downlink Control Channel) utilization in LTE networks. The dramatic challenge is related to very typical case when there is no signaling resources to assign the traffic channels for users. This problem is called blocked PDCCH. In this article we are going to show the results of simulation reflecting the LTE network...
PKD (Ka-band receiver) instrument, a part of science payload of “Luna-Glob” mission spacecraft, is designed for navigational task and “INGL” experiment. The “INGL” experiment involves a gravity field measurement around “Luna-Glob” and “Luna-Resource” moon probe landing locations. The instrument receives the landing module beacon signal to accurately and precisely measure the changes in the spacecraft...
