Abstract

Disclosed are a method and an apparatus for adaptive interference cancellation (IC), so as to solve a problem of incomplete benefiting of IC between signal processing devices, thereby improving system gain. The embodiments of the present invention comprises: selecting adaptively, according to IC capabilities of a first signal processing device and a second signal processing device in a same uplink receive resource group, an IC mode between the first signal processing device and the second signal processing device, the IC capability comprising: demodulation IC, or, decoding IC, or, not supporting IC; and determining, according to the IC mode, an IC processing manner of the first signal processing device and the second signal processing device, so that the first signal processing device and the second signal processing device perform IC on a received signal according to the IC processing manner.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for adaptive interference cancellation. Background technique [0002] Interference Cancellation (IC, Interference Cancellation) technology is a kind of Multi-user Detection (MUD, Multi-user Detection) technology. Its principle is that different user signals independently estimate the locally generated structure) to subtract part or all of the interference to the user signal from the received signal. Interference cancellation does not require a correlation matrix, and can be expanded without adding too much calculation, and can improve the user's reception performance for weak power signals. Therefore, the interference cancellation method is the first choice for the third-generation mobile communication system. Based on different sources of reconstruction information, ICs can be divided into demodulation ICs that perform reconstruction based o...
