1. , a kind of in digital radio system detection of call set up the method for pulse train, in described digital radio system, in predetermined time slot, set up calling by a certain call set-up burst that comprises known training sequence (200);

  • In described method, by the received signal of sampling is relevant with known training sequence, and, estimate the position and the energy of the maximum point of impulse response in the time slot by calculate the average energy of the maximum point of impulse response for each correlated results,It is characterized in that, for each correlated results, the energy that comprises in the correlated results of other sampling of average described time slot, calculate the ratio between the average energy of other sampling of the average ceiling capacity of described impulse response and described time slot, if and described ratio is higher than given threshold value, then judge in described time slot to receive call set-up burst.
