A method and apparatus for mitigating multipath interference in a digital signal correlator forms values representative of magnitude or power of a correlation response between a digital signal and a pseudorandom reference code. The structure includes a plurality of support tubes aligned substantially end-to-end and extending laterally to span the width of a vehicle body for the support of various instruments and devices within the panel. If the traffic load exceeds the first threshold V1, the provision of additional transmission capacity for new data signal connections stops. The first active device is controlled by a write through read signal.
