Method for the estimation of channel parameters in a wireless communication system. The demultiplexing system receives packets of a message, identifies a sequence of message handlers for processing the message, identifies state information associated with the message for each message handler, and invokes the message handlers passing the message and the associated state information. The bending arm is designed such that a contact region of the bending arm bears with prestress against a contact region of a wall of the housing in a mounted state within the housing. Charge conductors fixed to the contact array pass through or by the series connection such that a very compact device results. The invention is also directed to various method of transmitting a signal using a signal conduction matrix.
