Signal equalization with compensation for scrambling code correlation

A radio receiver arrangement in a Wideband Code Division Multiple Access system, comprising:

• a radio receiver, configured for receiving a digital radio signal spread by scrambling codes;
• and
• an equalizer, connected to said radio receiver, and comprising an equalizer core, a channel estimator and a combining weight estimator;
• said equalizer core configured for combining a plurality of part signals, deduced from said digital radio signal, with a respective delay and a respective combining weight, into an equalized digital radio signal wherein
• said combining weight estimator is configured for providing said combining weights to said equalizer core, said combining weights being based on a signal impairment matrix having elements compensated for systematic colouring caused by said scrambling codes.
