At least one embodiment relates to generating at least one RF signal based on at least one digital baseband signal at a first clock rate. At least one digital pulse sequence at a second clock rate corresponding to a center frequency of the RF signal is modulated based on the digital baseband signal. Pulses of the pulse sequence are quantized based on a time grid of a third clock rate. A ratio between a number of second clock cycles corresponding to one first clock cycle and a number of third clock cycles corresponding to one first clock cycle is non-integer.

Method and apparatus for generating at least one RF signal

An active transceiver array for a wireless telecommunications network. The transceiver array comprises a plurality of calibratable transceiver modules. Each transceiver module comprises a transceiver chain operable to process a primary signal and generate a processed primary signal; a comparator unit operable to compare said primary signal and said processed primary signal to determine a transceiver chain error induced by said transceiver chain in said processed primary signal; and a correction unit which uses the transceiver error to correct said primary signal to be processed by said transceiver chain.
