Abstract

The invention discloses a universal load-balancing algorithm of a wireless communication multi-mode terminal system. A decision feedback equalizer is included and comprises an IQ buffer, a forward-direction filter, an inverse filter, a feedback ring and a decision device; the IQ buffer is electrically connected with the input end of the forward-direction filter; the output end of the forward-direction filter is electrically connected with the input end of the decision device through the feedback ring; the decision device is provided with two output ends; one output end of the decision device is electrically connected with an external output device; the other output end of the decision device is electrically connected with the input end of the inverse filter; the inverse filter is also provided with two output ends; one output end of the inverse filter is electrically connected with the input end of the forward-direction filter. According to the product, partial multipath interference and inter-cell interference can be well resisted, and partial interface between multipaths in cells and inter-cell multiuser interference can be eliminated at the same time, so that the aim that the performance is greatly improved is achieved.

Description

technical field [0001] The invention relates to the field of communication, in particular to a general equalization algorithm for a wireless communication multi-mode terminal system. Background technique [0002] Baseband chips are the commanding heights in mobile phone chips, and have always been a battleground for international giants. Many manufacturers such as Texas Instruments and NVIDIA were eventually eliminated by the mobile phone market due to their uncompetitive baseband chips, but Qualcomm took the lead in the mobile chip market with baseband chips. Therefore, the baseband terminal chip is the core competitiveness of the manufacturer, and even determines the survival of life and death. Most users think that the performance of mobile phone CPU is reflected in processing speed and power consumption. In fact, in the era of smart phones, there is still one of the most basic and critical requirements - mobile phone signal quality. The signal quality of the mobile pho...
