SATELLITE COMMUNICATIONS SYSTEM UTILIZING PARALLEL CONCATENATED CODING.

摘要

A VSAT satellite communications network utilizes parallel concatenated coding on its inbound or outbound links, or both. For short data blocks, nonrecursive systematic tail-biting convolutional codes are used. These parallel concatenated coding techniques are used in conjunction with spread-spectrum modulation to provide a VSAT communications system which meets FCC regulations on the total power spectral density of transmitted signals as well as mitigates from adjacent satellites.
