With a steadily increasing number of mobile radio subscribers having to share limited frequency resources, operators are looking for economical ways to expand their network
capacity. An obvious approach is to use the available frequency spectrum as effectively as possible by employing a reuse factor of 1:1. This, however, involves considerable adjacent-channel interference, which would diminish the desired effect. One solution can be found in a new receiver technology: DARP (downlink advanced receiver performance).
