Single ended channel conditioning device


- The main objective is to develop a self-contained, very low volume, remotely powered signal conditioning subsystem to improve, for current DECT picocell system, the link quality in both directions of the communication in the wire interface between BS and BSC. The ultimate goal is to integrate this conditioning mechanism in a connector-like module for BS to BSC links allowing wire links up to 3 km.

- To demonstrate in field trials the performance and feasibility of the device.

Secondary goals whose achievement is crucial for accomplishment of the main goals are:

- To develop an ASIC capable of performing, in one single location, channel conditioning for bidirectional end-to-end links.

- To develop a high density DC/DC conversion module, incorporating advanced packaging of magnetic devices, to be included in the connector-like solution to allow remote powering for both functions in the conditioning device and BS from BSC.

- To demonstrate the signal conditioning architecture by means of a suitable feasibility model for the radio link, to achieve BER=10{-3} at 200 ns of delay spread.

The continuous growth of the subscriber base in current mobile systems, i.e. Digital European Cordless Telecommunication, (DECT), system provides a motive to seek new ways of increasing the capacity on offer. One approach is to improve signal quality by using advanced signal processing techniques. The added value of this approach with respect to already existing solutions, namely HDSL and ADSL, is that the signal processing will only be done at one line termination of the digital local line. This contrasts with HDSL that requires signal processing at both line terminations of the digital local line. The outcome of these activities will be a connector-like module attachable between Base Station (BS) and the wire towards the Base Station Controller (BSC). Improvement of the air interface of DECT with the same single-ended concept to make it robust against multipath propagation will also be addressed.
