Abstract

The invention provides a Gaussian white noise power measuring method, comprising the steps of determining whether valid Gaussian white noise power exists; if so, enabling current Gaussian white noise power to be equal to the valid Gaussian white nose power, obtaining an equalization coefficient according to the current Gaussian white noise power, performing equalization of a received signal according to the equalization coefficient, and obtaining a chip-level signal after equalization; performing descrambling for the chip-level signal after equalization and dispreading for a spreading code, and obtaining a detection signal; obtaining a symbol-level signal to interference plus noise power ratio after equalization according to the detection signal; and obtaining a chip-level Gaussian white noise power according to the symbol-level signal to interference plus noise power ratio after equalization.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a Gaussian white noise power measurement method and device. Background technique [0002] The WCDMA (Wideband Code Division Multiple Access) system is a broadband mobile communication system that uses orthogonal spreading codes to distinguish services and users. Because its transmission bandwidth is much larger than the coherent bandwidth of the space physical channel. Therefore, signal transmission in a WCDMA system is often accompanied by frequency selective fading, and the embodiment of frequency selective fading in the time domain is multipath transmission. [0003] RAKE is a common receiver in the WCDMA system. It combines the energy of the multipath components in the system transmission to improve the receiving signal-to-noise ratio, thereby estimating the transmission vector. This kind of receiver has a simple principle and does not consider the elimination of int...
