Frequency Plans for Satellite Transmission of Single Channel per Carrier (scpc) Carriers Using Non-linear Transponders in the Mobile-satellite Service
ثبت نشده
چکیده
considering a) a) that a number of SCPC (Single Channel Per Carrier) carriers are transmitted via a single satellite transponder in satellite communication systems; b) that, for efficient use of satellite power, the transponder would be operated in the near saturation region, in which case intermodulation noise affects signal quality; c) that the intermodulation products falling into the frequency slots of occupied signal channels could be reduced by suitably positioning the channels within the available bandwidth; d) that bandwidth-efficient frequency plans need to be developed; e) the analysis of intermodulation-minimum frequency assignment as described in Annex 1,

A Modular Multistage Approach to Digital Fdm Demultiplexing for Mobile Scpc Satellite Communications
A hierarchical multistage method (HMM) for digital clemultiplexing of an FDM signal composed of L adjacent SCPC signals is described; L is (preferably) a power of two, here L=32. This I-IMM approach to FDM dernultiplexing applies bandpass sampling and is based on the processing of complexvalued signals by linear-phase FIR filters, where at any stage of processing the respective signals are alwa...

The strawman PASS design calls for the use of a CONUS beam for transmission between the supplier and the satellite and for fixed beams for transmission between the basic personal terminal (BPT) and the satellite. The satellite uses a 3m main reflector for transmission at 20 GHz and a 2m main reflector for reception at 30 GHz. The beamwidth of the reflector is 0.35°. To cover CONUS 142 fixed bea...

In this thesis, we consider frequency assignment problems arising from an SDMA satellite communication system which consists of a satellite and a number of users distributed inside a fixed sized service area. The objective is to assign a given number of frequency carriers to as many users as possible. This assignment should not violate the incurred interference constraints. Two types of interfe...
