RECEIVER FOR SPREAD SPECTRUM

摘要

PURPOSE:To provide a receiver which can simplify the configuration of an interference wave removing circuit. CONSTITUTION:This device is provided with (n) pieces of inverse spread circuits 1-3 [(n) is an integer >=2], selector circuits 1-4 connected to the inverse spread circuits 1-3 and interference removing circuits 1-5 connected to the inverse spread circuits 1-3 and at the selector circuits 1-4, (n-1) pieces of output levels from the inverse spread circuits for performing the inverse spread of signals from an interference station, (m) pieces of outputs of the inverse spread circuits 1-3 [(m) is an integer <=(n-1)] from the largest absolute value of products between the spread codes of the respective inverse spread circuits 1-3 and the mutual correlation values of spread codes at a desired station and the outputs of the inverse spread circuits 1-3 at the desired station are connected to the interference removing circuits 1-5.
