Cross-talk estimating and compensating arrangement for use in frequency duplex transmission-/reception-arrangement in end terminal, has outputs connected with inputs of digital-analog converter and receiving signal processing arrangements

摘要

The arrangement (11) has an input connected with an output of a digital transmission signal generating arrangement (4). Outputs of the arrangement (11) are connected with an input of a digital-analog converter arrangement (10) and an input of a receiving signal processing arrangement (12), respectively. Transmission and reception branches (3, 2) have an output and an input connected with a duplexer (7). An output of the converter arrangement is connected with the input of the arrangement (12). An independent claim is also included for a method for compensating cross-talks of transmission signals on a reception branch in a frequency duplex transmission -/reception-arrangement.
