• Abstract:
  Workshop Objectives. This is the Second of Two Parts on Compatibility. Last time, OOBE. Today examine mitigation of Adjacent Band Interference, ABI. Apply Relevant TWG and NPEF (2011) data to engage compatibility analysis. Assert Principle: Dr. Brad Parkinson’s PTA, Protect, Toughen and Augment. Assert Principle: OOBE and ABI are distinct but parallel forms of interference. OOBE = Transmitter sideband emissions that fall into GPS receive bands. ABI governed by GPS receiver rejection of all nearby transmitted signals. Parallel process for success: Must solve and set OOBE and ABI rules together. Should not forget Intermodulation once OOBE, ABI are set.  Finding: Last time we covered the first compatibility factor, OOBE. We found that ATC offers optimum OOBE compatibility at -105 dBW/MHz Uses competitive, practical commercial components. OOBE sets a balanced performance threshold for ABI performance.
