SPREADING DEVICE AND DESPREADING DEVICE FOR RADIO COMMUNICATIONS IN THE PRESENCE OF AN OFF-AXIS POWER SPECTRAL DENSITY CONSTRAINT |
摘要 |
A device (D1) is dedicated to the processing of signals to be transmitted by waves, within a communication terminal (T). This device (D1) comprises i) memory means (M1) for temporarily storing a sequence of digital samples of an analogue input signal according to a first sampling frequency and in a manner synchronized with respect to starts of periodic time slots, and ii) digital/analogue conversion means (CV2) for generating, during each time slot and according to a second sampling frequency equal to N times the first sampling frequency, with N an integer strictly greater than 1, an analogue output signal, to be transmitted, representative of N repetitions of the sequence of digital samples that is stored in the memory means (M1) during the time slot concerned, so as to output the analogue signal according to a symbol rate equal to N times a reference symbol rate. |
