Embodiment Construction

[0040] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings. In the interest of clarity and conciseness, not all features of an actual implementation are described in this specification. It should be understood, however, that in developing any such practical embodiment, many implementation-specific decisions must be made in order to achieve the developer's specific goals, such as meeting those constraints related to the system and business, and those Restrictions may vary from implementation to implementation. Moreover, it should also be understood that development work, while potentially complex and time-consuming, would at least be a routine undertaking for those skilled in the art having the benefit of this disclosure.

[0041] Here, it should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only the device structure and / or processing steps closely related to the ...

Abstract

The invention discloses a multi-antenna wireless communication system and a transmitting method thereof. The method comprises the following steps of: dividing a plurality of antennae into two transmitting antenna groups; transmitting reference signals and data signals of the first transmitting antenna group in a mode that time frequencies of reference signals of transmitting antennae in the firsttransmitting antenna group are not superposed; and transmitting reference signals of the second transmitting antenna group in a mode that reference signals of the second transmitting antenna group are superposed on the transmitting signals of the first transmitting antenna group.

Description

technical field [0001] The present invention generally relates to the communication field, and more specifically, the present invention relates to a multi-antenna wireless communication system with multiple antennas and a sending method thereof. Background technique [0002] Multi-carrier wireless communication based on Orthogonal Frequency Division Multiplexing (OFDM) technology divides the frequency-selective fading wideband channel evenly into multiple frequency flat-fading channels, so that only a single-tap channel is required at the receiving end. Frequency equalizer, which greatly simplifies the equalization algorithm of the system receiver. [0003] On the other hand, in order to improve the transmission efficiency of the wireless communication system, multiple transmission-reception (Multiple Input Multiple Output, MIMO) antenna technology has become an inevitable choice for current and future wireless communication. In the MIMO-OFDM system, due to the use of multi...
