IQ data transmission apparatus and method

Abstract

The invention discloses an IQ data transmission device method, which comprises framing the IQ data to be transmitted by a transmitting terminal, and transmitting the IQ data frame based on RapidIO protocol; and receiving the frame including the IQ data by a receiving terminal based on RapidIO protocol and acquiring IQ data therefrom. Obviously, since the IQ data to be transmitted by the transmitting terminal is framed and transmitted based on RapidIO protocol, the receiving terminal can receive the frame including the IQ data based on RapidIO protocol and acquire IQ data therefrom. Therefore, the current IQ data conversion operation in a parallel period is obviated, thereby to effectively obviate the waste of logic resources. Besides, complex operation is not needed to be executed to IQ data of different formants in the transmission process between the transmitting terminal and the receiving terminal. Accordingly, the invention can be commonly used for a mobile communication system of different formats.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to an IQ data transmission device and method. Background technique [0002] Among the currently actively researched multi-mode co-site technologies, the baseband unit needs to support mobile communication systems of different standards at the same time, such as GSM, WCDMA, CDMA2000, TD-SCDMA, Wimax and so on. [0003] At present, 8B / 10B or 10B / 12B coded low-voltage differential signaling (LVDS) is basically used to transmit IQ data between boards of the baseband unit. The specific IQ data transmission principle is shown in Figure 1. In Figure 1, on the data sending end board, the IQ data is multiplexed and converted to parallel and serialized, and then sent out after encoding; on the switching board, the received IQ data is decoded to achieve synchronization, and then the IQ data Perform serial-to-parallel conversion, exchange the converted parallel data, and then send it out ...

AI Technical Summary

Problems solved by technology

[0004] It can be seen from Figure 1 that the exchange operation can only be completed in the parallel phase, and too many parallel processing operations will consume more logical resources

In addition, multi-mode base stations have flexible configuration requirements for multi-mode, coupled with different chip rates of different mobile communication systems, resulting in the need to perform different IQ data for different formats during the transmission process between the sending end and the receiving end. Therefore, the method of using LVDS to transmit IQ data is difficult to apply to mobile communication systems of different standards, which has the advantages of increased development complexity, more logic resources, flexibility that cannot meet requirements, poor upgradeability, and poor versatility. shortcoming
