Vehicle-to-vehicle communication and ranging system using code-hopping spread spectrum technique with code collision avoidance algorithm

We propose vehicle-to-vehicle communication and ranging system using code-hopping spread spectrum technique with code collision avoidance algorithm called code-hopping boomerang transmission system with a code collision avoidance algorithm. The is to do away with the problem of code collision of a code-hopping spread spectrum technique by the code collision avoidance algorithm.
