Transmitter, network node, method and computer program

Abstract:

A transmitter is arranged to transmit binary information using a binary amplitude shift keying where information symbols are represented by a signal including a first power state and a second power state. A duration of a bit includes a first part where the second power state is applied irrespective of which binary value being represented, and a second part where a binary value is represented by any of the first power and a third power state or a combination pattern of the first power state and the third power state. The first power state has a higher signal power than the second power state and the third power state. The duration of the second part is equal or less the duration of the first part and the signal power of the first power state is such that the binary values are distinguishably decodable.
