Abstract

A method for reducing interference combines soft symbols using existing processing devices. In particular, transmitted data signals are received over a plurality of paths. The received data signal includes an interference component. The received data signals are processed to provide a plurality of soft symbols that correspond to the transmitted data signal. The plurality of soft symbols are combined to reduce the interference component of the data signal and provided output signal that corresponds to the transmitted data signal. Accordingly, existing equalizers and combiners may be used to reduce interference. Related mobile user terminal and receivers are disclosed.

Description

field of invention [0001] The present invention relates to the field of communication, in particular how to reduce interference. Background of the invention [0002] Radio communication systems, such as cellular communication systems, are often used to provide voice and data communication to multiple receivers or users. Analog cellular systems such as AMPS, ETACS, NMT-450 and NMT-900 have been successfully developed worldwide. More recently, digital cellular systems such as IS-54B and IS-136 in North America and GSM in Pan-Europe have been introduced. These systems and others are described, for example, in the book entitled "Cellular Radio Systems" by Balston et al., Artech Press, Norwood, Mass., 1993. [0003] Frequency reuse is often used in cellular technology, where groups of frequencies are allocated to limited coverage areas called cells. Cells comprising the same frequency group are geographically separated from each other, and receivers in different cells can simu...
