Embodiment Construction

[0111] The drawings show preferred embodiments of the present invention, and the same reference numerals in the drawings correspond to the same or corresponding parts in the various drawings.

[0112] The Gaussian Minimum Shift Keying (GMSK) modulation system can be modeled as a single-input dual-output system in the real domain. This mode is a virtual single-channel transmit 2-channel receive system. The multi-antenna interference cancellation technology can be applied to the GMSK system provided by the embodiment of the present invention, and the GMSK system can fully meet the above requirements and other requirements. The invention provides a multi-branch equalizer processing module capable of eliminating interference signals in received radio frequency pulses. The multi-branch equalizer processing module includes a plurality of equalizer processing branches. An equalizer processing branch is capable of training based on known training sequences and equalizing the receive...

Abstract

The present invention provides a multi-branch equalizer processing module and a method to cancel interference associated with received radio frequency (RF) bursts. This multi-branch equalizer processing module includes: a first equalizer processing branch which is operable to process training based upon known training sequences and equalize the received RF burst, and extract data bits from the received RF burst; a second equalizer processing branch which is operable to be trained based upon known training sequences and re-encoded data bits which are generated by processing decoded frame, equalize the received RF burst, and extract replacement data bits. The method includes training the first equalizer by utilizing the known training sequences of the received radio frequency (RF) bursts, thereafter performing equalizing, deinterlacing, decoding, extracting data bits, recoding to generate the recoding pulse and training the second equalizer processing branch by utilizing re-encoded bursts.

Description

technical field [0001] The present invention relates to a cellular wireless communication system, and more specifically, relates to a technique for a wireless terminal of the wireless communication system to process received data information to eliminate interference. Background technique [0002] Cellular wireless communication systems provide wireless communication services to many populated areas around the world. Cellular wireless communication systems were originally built to serve voice communications, but are now also used to support data communications. The demand for data communication services has been stimulated by the recognition and widespread use of the Internet. Data communications have historically been served over wired connections, but cellular wireless users are now demanding that their wireless devices also support data communications. Many wireless users desire to be able to surf the web, send and receive email, and perform other data communication act...
