Data processing method and device for hybrid networking

Abstract

The invention relates to a data processing method and a data processing device for hybrid networking. The data processing method comprises the following steps: processing an MIMO user data and a non-MIMO user data to acquire a first input data borne on a main pilot channel and a second input data borne on an auxiliary pilot channel, wherein the first input data comprises the non-MIMO user data; performing mapping processing of balanced power on the first input data and the second input data to acquire a first output data and a second output data borne on radio-frequency channels; and sending the first output data and the second output data to a forward emission channel. The method and the device map two paths of data comprising MIMO and non-MIMO user data in a base band to the radio-frequency channels to effectively ensure power balance of two radio-frequency channels by adjusting the power on the premise of ensuring the MIMO and non-MIMO user receiving performance.

Description

technical field [0001] The invention relates to a networking method and device for a communication system, in particular to a data processing method and device for hybrid networking. Background technique [0002] The Multiple-Input Multiple-Output (MIMO) system uses multiple transmitting antennas and receiving antennas at the transmitting end and receiving end respectively, and signals are transmitted and received through multiple antennas at the transmitting end and receiving end, thereby improving Quality of service per user, such as bit error rate or data rate. Although the MIMO system is considered to be one of the main data transmission technologies in the future, the Single-Input Single-Output (SISO) system is still widely used in traditional systems, and this coexistence situation will continue for a while. time. [0003] When the MIMO system and the traditional system are mixed into a network, the non-MIMO system can use the Space Time Transmit Diversity (STTD) mod...

Problems solved by technology

However, due to the high consumption of the STTD mode, using the STTD mode means that the user terminal cannot use an equalized receiver. In a channel environment with a high signal-to-noise ratio (SNR), the receiving performance of non-MIMO users is 30% higher than that of using the SISO mode. 40% drop

In order to solve the problem of user reception performance degradation, the prior art proposes a solution for non-MIMO users to transmit in SISO mode on the main antenna of the MIMO system, but the mixed use of SISO mode and MIMO mode results in two radio frequency channels power imbalance, and the MIMO mode signal on the auxiliary antenna will interfere with the SISO mode signal, which also causes the reception performance to decline
