Half tone offset may be utilized to mitigate signal distortion caused by DC bias within OFDM-based systems. In addition a cyclic prefix may be utilized within an OFDM-based system to mitigate inter-symbol-interference. Presented herein are techniques and methods to efficiently apply a cyclic prefix to an OFDM symbol with a half tone offset.

Efficient cyclic prefix generation with half tone offset

Effects of communications blockages can be mitigated. A wireless communication transmitter comprises a processor and a memory. The memory stores instructions executable by the processor to, upon receiving a current data packet in a sequence of data packets, wirelessly transmit a burst to a second computer. The burst includes the current data packet and a previous data packet in the sequence.

Satellite blockage tolerant communication

Half tone offset may be utilized to mitigate signal distortion caused by DC bias within OFDM-based systems. In addition a cyclic prefix may be utilized within an OFDM-based system to mitigate inter-symbol-interference. Presented herein are techniques and methods to efficiently apply a cyclic prefix to an OFDM symbol with half tone offset for low power systems.

A system for slidable connection of a satellite antenna to a mobile radio comprising: the satellite antenna including a satellite antenna element and at least one antenna contact coupled thereto; and at least one slide strip, slidably coupled with the at least one antenna contact when the antenna is in a plurality of retracted positions, the at least one slide strip being coupled to a transceiver in the mobile radio and conducting radio-frequency signals to maintain communication with the mobile radio. A method for slidable connection of an antenna to a mobile radio comprising the steps of: providing a satellite antenna and at least one antenna contact coupled thereto; providing at least one slide strip coupled to a transceiver and configured to be slidably coupleable with the at least one antenna contact; sliding the satellite antenna into a plurality of retracted positions and connecting the at least one antenna contact with the at least one slide strip, wherein the satellite antenna maintains a connection to the transceiver while sliding through the plurality of retracted positions.
