Embodiment Construction

[0051] Such as figure 1 In the present invention, the transmitting device is composed of a serial-to-parallel conversion module, a linear conversion module, a shaping filter bank, a multi-antenna multiplex transmission module, a cyclic prefix module and a radio frequency transmission module connected in sequence.

[0052] The serial-to-parallel conversion module 1 has an output terminal connected to the linear conversion module 2 and is used to convert the modulated serial symbol data sequence into a parallel symbol data sequence.

[0053] The linear transformation module 2 is connected to the output terminal of the serial-parallel transformation module 1, and is used to perform FFT transformation on the input data symbols and map them to multiple subbands for transmission. On the one hand, the frequency multiplexing gain can be obtained, and on the other hand, the The peak-to-average ratio of the transmitted signal.

[0054] The shaping filter bank 3, connected to the output of the...

Abstract

The invention provides a multi-antennae multiplexing receiving device based on GMC, which comprises a radio frequency receiving module, a synchronous and channel estimation module, a circulation removing module, a series-parallel conversion module, a frequency domain equilibrium module, a first parallel-serial conversion module, a matching filter group, a linear inverse transformation module and a second series-parallel conversion module, wherein the frequency domain equilibrium module is connected with output ends of the series-parallel conversion module and the synchronous and channel estimation module; the first parallel-serial conversion module is connected with the output end the frequency domain equilibrium module; the matching filter group is connected with the output end of the first parallel-serial conversion module; the linear inverse transformation module is connected with the output end of the matching filter group and used for restoring signals transmitted by various sub bands to a time domain; and the second series-parallel conversion module is connected with the output end of the linear inverse transformation module, and used for converting the input parallel data sequence into the output data sequence and restoring serial signs on original constellation points. The receiving device greatly reduces the expenditure of the system.

Description

[0001] This application is a divisional application for an invention patent with the application number 200510111450.9, the filing date of December 13, 2005, and the title of the invention for the GMC-based multi-antenna multiplexed transmission and reception device and frequency domain equalization method. Technical field [0002] The present invention relates to a multi-antenna multiplexing receiving device based on GMC, especially a wireless communication system in which symbols on the constellation diagram after modulation and mapping cannot be obtained when equalizing processing is performed at the receiving end, and multi-antenna multiplexing receiving under fading channel conditions Device. Background technique [0003] Multiple input multiple output MIMO (Multiple Input Multiple Output) multi-antenna technology is an important way for future mobile communication systems to achieve high data rates and improve transmission quality. It is one of the major breakthroughs in mode...
