Embodiment Construction

[0022] figure 1 Shows a schematic block diagram of a receiving unit in a communication device which can be integrated as a transmitting, receiving or transmitting / receiving device in a distributed base station network, especially in a local broadband network or a digital broadband local network. If the communication device is to be included in the exchange of information on the network as determined by the use requests received by the communication device at a specific time, then the communication device has the task of finding a transmission channel for the information exchange, which transmission channel is at a specific time The time is free with the participation of the communication device, ie available for information or data exchange.

[0023] In this case, the usage request is generated either by the user of the communication device or by one of the other distributed base stations in the network. In both cases, ie a request for use by a user and a request for use by a...

Abstract

The invention relates to a receiving unit for searching for at least one unused transmission channel in a communications device in a network of distributed stations and / or for monitoring transmission channels such that specific messages can be determined for that communications device, and to a method for its use, in particular in a local broadband network or a digital broadband home network. The receiving unit comprises a filter unit (5), which has a broadband reception characteristic in a monitoring mode, such that signals from a number of transmission channels can be received in parallel; a digital filter device (7) for subdividing a broad filter band, which has passed through the filter unit (5), into a number of component signals which each have a narrower bandwidth than broadband signal and can each be associated with one of the number of transmission channels; and an evaluation device (9) in order to determine at least one signal strength for each of the number of component signals so that it is possible to decide which of the number of transmission channels is or are being used and / or which of the number of transmission channels is or are not being used.

Description

technical field [0001] The invention relates to a receiving unit for finding at least one unused transmission channel in a communication device in a distributed base station network, in particular in a local broadband network or a digital broadband local network, and to a method of using the receiving unit . Background technique [0002] In the operation of a local broadband network or a digital broadband local network, the devices integrated in the respective networks have to find transmission channels for transmitting information in the network, and select channels that are idle or unused within a certain transmission time . If there is a need for transmission, the respective networks can use these idle transmission channels for data or information transmission. [0003] Furthermore, it is necessary for the devices integrated in the network to identify and select the transmission channel containing the information to be sent to each device in the network. Conventional d...
