Method for the transmission of signals in a communication system, digital mu00ecdia storage that can be read by the computer, transmitter for a digital communication system, a base station of a wireless communication system digital and mobile station of a communication system Will digital wireless.This is a method to increase the reliability of channel estimation in a digital communication system by reducing ambiguity in recognition of the symbols received are evaluated to estimate the channel.A first plurality of bits is mapped to a modulation state according to a given mapping of gray to binary numbers to the state of the modulation and it is transmitted.The plurality of bits is retransmitted at least once, with a subset of bits contained in the plurality of bits inverted, and mapped to the additional modulation in accordance with the same mapping of gray.The bits to be inverted are determined in a way such that the number of results of different sum of vectors can be obtained for all combinations of values of bits within the first plurality of bits, by adding the vectors that represent complex values of the first The state of modulation and the modulation calls in a complex plane.Is lower than the number of states of different modulation within the mapping of gray.
