A link interface for the telecommunications system

摘要

The present invention refers to a link interface interconnecting a first unit (BSC) and a second unit (BTS) of a telecommunications system. The interface comprises: a first link (L1) to connect transmitting means (10) in the first unit (BSC) and receiving means (20) in the second unit; and a second link (L2) to connect transmitting means (21) in the second unit (BTS) with receiving means (11) in the first unit. The first unit (BSC) comprises equalising means (13) to equalise a signal received from said second unit (BTS). The interface is characterised in that the first unit (BSC) comprises predistortion means, the coefficients of which are calculated as a function of data transmitted from said second unit (BTS) to said first unit (BSC) on said first link (L1).
