Abstract:
Apparatus for determining an offset of a spread spectrum signal spread with a pseudonoise code, comprising:a pseudonoise code generator for generating the pseudonoise code;delay means, receiving the pseudonoise code from said pseudonoise code generator, for generating a first plurality of delayed pseudonoise codes each delayed by a different amount;a first despreading means receiving the spread spectrum signal and receiving the pseudonoise code from said pseudonoise code generator, for producing a first despread signal;a first plurality of despreading means, each of said first plurality of despreading means receiving the spread spectrum signal and receiving a respective one of said first plurality of delayed pseudonoise codes for producing a first plurality of despread signals; anda processor, receiving the first despread signal and the first plurality of despread signals, for combining the despread signals to produce an offset signal.
