Abstract

In a time division multiple access (TDMA) system, for "multi-path" data communication via satellite repeater, the form of transmitted data is varied adaptively to maintain error-free transmission under varying noise conditions. Adjustments are made on a path selective and channel selective basis to protect only the most vulnerable data in specific transmission paths experiencing noise deterioration. Accordingly any multi-channel burst may contain channels of data in both protected and unprotected forms. A predetermined portion of each channel containing data in unprotected format is used explicitly to designate the destination of the accompanying data and implicitly to distinguish the data format as unprotected. In protected format data including error protective coding is transmitted in two contiguous channels along with information in the first channel explicitly distinguishing the protected format. This format-distinguishing information occupies the space allotted in the unprotected format for designating the data destination. The destination of protectively encoded data is explicitly designated in a separate predetermined space in the associated double-channel slot.
