Abstract:
1. A method for computing cubic metric used for performing Maximum Power Reduction in a transmitter of a user equipment communicating with a base station, said cubic metric computation being performed before each time slot of an uplink transmission of data, said method comprising: using pseudorandom number generators for generating random data which are used for performing said cubic metric computation, and using the result of said computation for applying said Maximum Power Reduction for each time slot of said uplink transmission; wherein the method further comprises generating at least one random signal by using the pseudorandom number generators, said random signal being equivalent to a real signal; spreading the generated random signal to associated channels; weighting the spread random signal by gain factors; mapping the weighted random signal to In-phase (I) and Quadrature (Q) channels; scrambling the mapped random signal by a complex-valued scrambling code so as to provide a complex chip stream; normalizing the complex chip stream; upsampling and filtering the normalized complex chip stream; and performing Cubic Metric calculation of the normalized complex chip stream, by calculating (V wherein (V
