    摘要: A wireless telecommunications network comprises a first terminal (2) and a second terminal (UE), the second terminal including a receiving stage and a processor (10) operative to process signals received from the first terminal and to determine received signal quality. The second terminal also includes a transmitter (Tx) operative to send a feedback signal (QI, RAI) dependent upon the received signal quality to the first terminal provided the change in received signal quality is determined as being more than a predetermined amount.

    摘要: A mobile telephone system includes a base station which establishes a link with a selected mobile station. The received signal from the mobile station will include a noise component as well as a possible interference component from another mobile station operating at the same frequency in another cell.
    The base station has a trellis based equalisation system which operates on the assumption that the received signal includes components which have a predominantly Gaussian characteristic. A switch controller determines when the interference component (which is non-gaussian) in the received signal becomes a dominant component and operates to switch a spatio-temporal filter into the circuit instead of the trellis based equalisation system, to improve the bit error rate performance.
