Abstract

The present disclosure relates to the detection of active spreading codes and modulation schemes. A channelization code analyzer for determining an active channelization code includes: a despreading unit configured to despread a received signal with a plurality of candidate channelization codes to generate a plurality of despread signals. The channelization code analyzer also includes a detector configured to detect a set of despread signals having a predetermined modulation scheme from among the plurality of despread signals. The channelization code identification unit is configured to identify at least one active channelization code from a plurality of candidate channelization codes based on the set of detected despread signals. Additionally, a radio receiver arrangement, a second and fourth time instant processing unit, and a modulation scheme detector are described.

Description

technical field [0001] Embodiments described herein relate generally to the field of radio communications, and more particularly to techniques for detecting active spreading codes and / or modulation schemes in radio receivers of radio networks, particularly cellular radio networks. Background technique [0002] Radio networks use channelization to separate the different physical channels over which signals are transmitted. The channelization codes used by the base station(s) to signal other users are generally unknown to a particular user. In general, knowledge about the channelization codes assigned to other users can be beneficial for a particular user. [0003] By way of example, the cellular performance of a radio receiver may be limited by interference from signals assigned to other users. Reducing this interference can improve the signal-to-noise ratio at the receiver and can improve data throughput. One way to reduce this interference may rely on reconstructing the ...
