Cyclical obstruction communication system

摘要

Techniques for improving data rates at mobile terminals that are subject to periodic channel interruptions in a beyond-line-of-sight communication system are disclosed, including improved encoding and decoding systems that identify blockages and modify receiver operation during blockages to reduce data errors. In certain embodiments, encoding, symbol mapping, interleaving, and use of unique periodic identifiers function to enable a series of packets that may be received in a blockage impaired channel with reduced errors.

1. A method comprising:
establishing a communication session with a terminal via an intermittently obstructed channel in a wireless communication system; identifying blockage characteristics associated with the intermittently obstructed channel; determining communication parameters for communication with the terminal via the intermittently obstructed channel based on the blockage characteristics; communicating first data signals of the communication session with the terminal via the intermittently obstructed channel according to the communication parameters; identifying a change in the blockage characteristics; updating the communication parameters based on the identified change in the blockage characteristics; and communicating second data signals of the communication session with the terminal via the intermittently obstructed channel according to the updated communication parameters.
