摘要： An apparatus and a method for estimating a Noise and Interference (NI) power in a communication system are provided. The method includes, calculating average values of impulse responses according to ranging codes, through use of a ranging signal sequence received through a resource allocated to a ranging channel, arranging the average values of the impulse responses according to ranging codes in order of the highest value to the lowest value, and multiplying a ranging code, which corresponds to an impulse response having an (x+1)th peak value among the arranged average values of the impulse responses, by a specific threshold value, and estimating the NI power, wherein “x” represents a number of ranging codes which can be simultaneously received by one ranging channel.

摘要： An apparatus and a method for decoding bits of a received signal in a communication system are provided. The method includes determining path metrics of respective states in a trellis corresponding to the received signal, selecting a start state in the trellis for a traceback in a last window of the trellis, repeating the traceback at least twice within the last window, and when the repeating of the traceback is completed, determining the decoded bits of the received signal using a survived path of a last traceback.
