The invention provides a method a system for processing OAM (operation, administration and maintenance) detecting results in an MPLS-TP (multiple protocol label switching-transmission parameter) network. The method includes following steps: receiving CCM (confidential code message); processing the CCM to obtain a processing result; judging whether the processing result has errors or not, if yes, entering a subsequent step, namely processing, and if not, stopping processing; judging whether the error type needs to copy the message to be sent a CPU (central processing unit) or not, if yes, sending the message, and if not, stopping processing; judging whether the error type needs to be recorded in an ErrorCache and reported the errors through the ErrorCache or not, if yes, performing ErrorCache processing, and if not, stopping processing; and judging whether the error type needs to report the errors by sending quick switching information, if yes, marking the errors with needs to send the quick switching information, and if not, stopping processing. Consequently, one or multiple error informing mechanisms can be provided flexibly and diversely aiming at different error types to meet requirements of the system.

The vehicle radar system of the present invention can simultaneously meet the system requirements of the LCA system, the DOW system, the RCTA system and the BSD system, thereby reducing the production cost and the complexity in system integration.

The present invention provides a demodulation method in which the N-order Viterbi idea is applied to the M-GFSK phase domain, by applying the Viterbi idea to the M-GFSK phase domain and using complex multiplication in the traditional Viterbi method when calculating the path increment , Addition and subtraction are replaced by real number subtraction, which reduces the computational complexity and improves the bit error rate performance of the system. The receiving end calculates the photopic distance of the additional cumulative phase matrix corresponding to the additional cumulative phase sequence and the reference state, and performs different iterations according to the number of executions of the present invention through the Viterbi idea, and obtains the minimum photopic distance buffer matrix and the minimum photopic distance row number Index cache matrix. According to the minimum value index of the Nth row vector of the minimum apparent distance cache matrix, the minimum apparent distance row number index matrix is ​​traced back to the first row vector, and the original is demodulated according to the mapping relationship between the index value corresponding to the first row and the symbol symbol. The invention calculates the maximum likelihood path and improves the performance of demodulation in the phase domain.
