Abstract: A method in connection with digital mobile radio communication systems for forming, in a receiver, a quality measure SQ of the signal vector received in a signal burst comprises forming a first estimate E.sub.s of the energy of the useful signal of the signal vector, forming a second estimate E.sub.n of the energy of the remaining signal components of the signal vector, and forming the quality measure SQ of the signal vector in accordance with the formula SQ=K.sub.1 E.sub.s /(K.sub.2 +E.sub.n), where K.sub.1 and K.sub.2 are predetermined constants.

Abstract: An anhydrous transdermal composition is disclosed comprising in a 20 to 100% lyotropic liquid crystalline arrangement:5 to 15 weight % of optically active or racemic N-methyl-N-(1-phenyl-2-propyl)-2-propynylamine or N-methyl-N-{1-(4-fluorophenyl)-2-propyl}-2-propynylamine or a pharmaceutically acceptable salt thereof;40 to 70% by weight of liquid polyethylene glycol;10 to 20% by weight of solid polyethylene glycol;2 to 30% by weight of a nonionic surface active agent;2 to 20% by weight of propylene glycol, and if desired,0.5 to 2% by weight of a polymer, the a value of which is greater than 0.6, andoptionally, in an amount needed up to 100% an emulsifying agent.
