    摘要: The invention relates to a cellular radio system wherein a communication terminal receives servo power instruction from a base station with which a radio communication comprising first uplink and downlink channels is established. In response to an instruction for changing a channel (13), the terminal records a first power level received from the base station and a reference power on which the terminal transmitted when the instruction was received. The terminal endeavours to continue communication on new uplink and downlink channels interrupting the transmission on the first uplink channel. If failed, the terminal evaluates a second power level received from the base station and restarts to transmit through the first uplink channel at a power determined according to the reference power and a variation between the first and second power level.

    摘要: Discrete symbols of transmitted signals, forming part of the components of a vector D of size N, are estimated from a vector Y of L digital samples of a received signal. The vector Y may be broken down into Y=AD+YN, where A is a matrix of size L×N previously determined from measurements of at least one transmission channel reply and YN represents a vector of L noise samples. The method includes determining an upper triangular matrix T of size N×N and a vector Z of size N such that the quadratic criteria ∥TX−Z∥2 and ∥AX−Y∥2 are minimal for the same vector X of size N, and dividing the vector Z and the matrix T into blocks so as to operate a minimisation of the quadratic criterion block by block along the diagonal of matrix T.
