Abstract:
A correlation apparatus including a sequence generator configured to generate a non-repeating preamble sequence which changes during each of a plurality of time epochs. The correlation apparatus includes a fallthrough correlator having a tapped delay line for receiving a set of complex-valued samples of a received signal. Each of a plurality of complex multipliers of the correlator is coupled to one of the delay line taps. Each multiplier multiplies, during one of the plurality of time epochs, one of the complex-valued samples of the received signal by one of a plurality of matched filter coefficients corresponding to the preamble sequence. A summation module includes a plurality of adders where a last of the plurality of adders outputs a correlation signal. A peak value of the correlation signals exceeds a threshold value when a sufficient correlation exists between the received signal and the values of the preamble sequence.

Claim (Index 10):
A method for correlating a sampled version of a received signal with a non-repeating preamble sequence, the method comprising:\n generating the non-repeating preamble sequence wherein the non-repeating preamble sequence changes during each of a plurality of time epochs; receiving a set of complex-valued samples of the received signal using a tapped delay line wherein the tapped delay line includes a plurality of taps and wherein each of the plurality of taps is separated by one of a corresponding plurality of delay elements; for each of the complex-valued samples of the received signal, performing a complex multiplication by multiplying the complex-valued sample of the received signal by one of a plurality of matched filter coefficients using one of a plurality of complex multipliers wherein the plurality of matched filter coefficients correspond to values of the preamble sequence during one of the plurality of time epochs; summing results of the complex multiplications to provide a correlation signal wherein a peak value of the correlation signal exceeds a threshold value when a sufficient correlation exists between the set of complex-valued samples of the received signal and the values of the preamble sequence.
