Abstract
In a system (e.g. a IR or RF based wireless remote control system) comprising a number (N) of non-synchronized transmitters that transmit respective signals, a method of transmitting data in packets to a receiver, comprising the steps of: transmitting the respective signals, said signals having repeated burst periods that are separated by quiescent periods and repeated with mutually different repetition period, wherein the burst periods have substantially the same length, BL, and each burst period comprises a data packet. The method is characterized in that (I) where N denotes the number of transmitters, n is an index denoting a respective one of the N transmitters, RPn is the repetition period for a transmitter with index n, and BL is the length of the burst periods.

In a system comprising a number (N) of non-synchronized transmitters that transmit respective signals, a method of transmitting data in packets to a receiver, comprising the steps of:
- transmitting the respective signals, said signals having repeated burst periods that are separated by quiescent periods and repeated with mutually different repetition periods,
- wherein the burst periods have substantially the same length, BL, and each burst period comprises a data packet;
- and
- wherein the repetition periods, RPn, are configured such that a succession of at most N−1 transmissions interfere with other of the respective signals wherein
- 2·N≦RPn/BL<2·[(N−1)2+n]
- where N denotes the number of transmitters, n is an index denoting a respective one of the N transmitters, RPn is the repetition period for a transmitter with index n, and BL is the length of the burst periods.

- where N denotes the number of transmitters, n is an index denoting a respective one of the N transmitters, RPn is the repetition period for a transmitter with index n, and BL is the length of the burst periods, and
- further comprising the step of encoding digital values of a block of two or more data bits, to be transmitted, by transmitting two consecutive pulses with a temporal distance, selected from a set of distances, each of which is associated with a digital value.
