Abstract

The present invention is related to a frequency hopping TDMA rado transmission system and enables frequency hopping to be performed for subsequent timeslots within the same TDMA-frame. It is directed to a transmitter, a receiver, a method for transmitting and a method for receiving. According to the invention a frequency channel to hop on is selected by means of a pointer that is set to point at a new frequency channel in a list of frequency channels. For each subsequent burst to be transmitted a new frequency channel is selected. Two frequency synthesizers are alternately tuned into the selected frequency channel and alternately used by the transceiver for transforming a base band burst to the radio frequency channel.
