Multi-standard communication

A communication node in a wireless communication system for improving signal handling, the communication node arranged to receive signals from at least one antenna and being configurable as a WCDMA receiver, the communication node comprising:

• a receiver arranged to receive two or more continuous WCDMA signals from one of the at least one antenna;
• a splitter arranged to split the two or more continuous WCDMA signals into windowed signals;
• and
• a processor arranged to execute a frequency domain conversion of the two or more windowed signals and to cause the communication node to:
• extract a pilot signal from the two or more continuous WCDMA signals;
• split the pilot signal into windowed pilot signals;
• perform a frequency domain conversion of the windowed pilot signals;
• provide a channel estimate of the frequency converted windowed pilot signals;
• provide diversity combined signals based on the frequency converted windowed signals of the continuous WCDMA signals and the channel estimate;
• and
• combine the diversity combined signals to provide a continuous signal.

A method in a communication node in a wireless communication system for improving signal handling, the communication node arranged to receive signals from at least one antenna and configured as a WCDMA receiver, the method comprising:

• executing a frequency domain conversion for two or more antenna signals from the at least one antenna, comprising:
• receiving a continuous signal from one of the at least one antenna;
• splitting the continuous antenna signal into windowed signals;
• adding an overlap to the windowed signals;
• and
• performing a frequency domain conversion of the windowed signals;
• providing a channel estimate based on a frequency converted pilot signal comprising:
• extracting a pilot signal;
• splitting the pilot signal into windowed pilot signals;
• adding an overlap to the windowed pilot signals;
• performing a frequency domain conversion of the windowed pilot signals;
• and
• providing a channel estimate of the frequency converted windowed pilot signals;
• providing diversity combined signals, comprising:
• performing diversity combining based on the frequency converted windowed signals of the two or more antenna signals and the channel estimate;
• and
• performing a time domain conversion of the diversity combined signals
• combining the diversity combined signals to provide a continuous signal.
