Abstract
A correlation device and method for different modulated signals such as BPSK signal and BOC signal. According to the present invention, the correlation device has one or more sections. Each section comprises a correlation unit for executing correlation; a first signal path for passing a received signal directly to the correlation unit; a second signal path for transferring a BOC signal into a BPSK-like signal and passing the signal to the correlation unit. The correlation unit has a multiplexer for selecting to allow an output of one of the first and second signal paths to be subject to signal correlation. The correlation results of the respective sections can be combined.
