1. A method of operating a digital mobile radio communications system in which pilot symbols are used for channel equalisation and in which synchronisation symbols are used to indicate burst timings, the method comprising:
using a sequence of pilot symbols, a sequence of synchronisation symbols, or a sequence of pilot symbols and synchronisation symbols in a transmission to indicate to a receiver the presence of stealing in the transmission; including a normal sequence of pilot symbols, synchronisation symbols, or pilot symbols and synchronisation symbols in a transmission when stealing is not present; and when stealing is present, including the stealing sequence of pilot symbols, synchronisation symbols, or pilot symbols and synchronisation symbols in the transmission in place of a normal sequence of pilot symbols, synchronisation symbols, or pilot symbols and synchronisation symbols; wherein the normal sequence of pilot symbols, synchronisation symbols, or pilot symbols and synchronisation symbols is distinct from the stealing sequence of pilot symbols, synchronisation symbols, or pilot symbols and synchronisation symbols; wherein the stealing sequence of pilot symbols, synchronisation symbols, or pilot symbols and synchronisation symbols is arranged to be distinguishable from the normal sequence of pilot symbols, synchronisation symbols, or pilot symbols and synchronisation symbols prior to equalisation. |
