Abstract

Embodiments of the invention relate to a method used for channel estimation and communication equipment. The method used for channel estimation comprises the following steps of receiving a first pilot signal using multi-subcarrier transmission on a frequency, wherein a predetermined number of subcarriers is separated among multiple subcarriers; averagely dividing the first pilot signal into a plurality of first pilot subsignals according to a time sequence, wherein a number of the first pilot subsignals is determined based on a predetermined number; and executing the channel estimation at least partially based on the plurality of first pilot subsignals. Corresponding communication equipment is also disclosed.

Description

technical field [0001] Embodiments of the present disclosure generally relate to communication technologies, and more specifically, to methods and communication devices for channel estimation. Background technique [0002] Vehicle-to-vehicle (V2V) communication technology, as an emerging communication technology, has received extensive attention from standardization organizations such as the Third Generation Partnership Project (3GPP). Using V2V technology, it can provide wireless communication based on PC5 interface for fast-moving vehicles. In order to meet the requirement of moving speed for inter-vehicle communication, it has been proposed that V2V technology needs to support a relative speed of up to 500 km / h. [0003] However, as the vehicle moves faster, the radio channel conditions experienced by the inter-vehicle communication also change faster in time, which for example causes the Doppler shift of the radio channel to become higher and the time-selective fading t...
