Problems solved by technology

Therefore, this solution cannot solve the problems faced by the IFD system
[0010] To sum up, the IFD system in the prior art has the disadvantage of relative delay caused by the signal transmission distance, which leads to the technical problem that the system cannot perform channel estimation

Embodiment 1

[0075] Embodiment 1 of the present invention proposes an information processing method, such as image 3As shown, the specific process of the method is as follows:

[0076] Step 31: Obtain the signal to be transmitted at the local end through the transmitter at the local end, insert the first pilot frequency and the second pilot frequency into the signal to be transmitted at the local end, and transmit it.

[0077] Step 32, obtain the local transmission signal through the local receiver.

[0078] Step 33, obtain the transmission signal of the opposite end through the receiver of the local end.

[0079] Step 34, analyze the transmitted signal of the local end and the transmitted signal of the opposite end through the receiver of the local end.

[0080] Wherein, in step 31, the first pilot is inserted from the first position of the signal to be transmitted at the local end, and the second pilot is inserted from the second position of the signal to be transmitted at the local e...

Embodiment 2

[0193] Based on the same inventive concept, Embodiment 2 of the present invention proposes an information processing device, including:

[0194] The local transmitter 901 is configured to obtain the signal to be transmitted at the local end, insert the first pilot frequency and the second pilot frequency into the signal to be transmitted at the local end and transmit it; wherein, the first pilot frequency is from the signal to be transmitted at the local end The first position is inserted, the second pilot is inserted from the second position of the signal to be transmitted at the local end, and there is a first preset time interval between the first position and the second position;

[0195] The local receiver 902 is configured to obtain the local transmission signal;

[0196] The local receiver 902 is also used to obtain the transmitted signal of the opposite end, and the transmitted signal of the opposite end is sent after inserting the third pilot and the fourth pilot; whe...

Abstract

The invention discloses an information processing method and device. The signal to be transmitted at the local end is obtained through the transmitter at the local end, and the first pilot frequency and the second pilot frequency are inserted into the signal to be transmitted at the local end and transmitted; wherein, the first pilot frequency The frequency is inserted from the first position of the signal to be transmitted at the local end, and the second pilot is inserted from the second position of the signal to be transmitted at the local end, and the first position and the second position are separated by a first preset duration; through the local receiver Obtain the transmission signal of the local end; obtain the transmission signal of the opposite end through the receiver of the local end, and the transmission signal of the opposite end is sent after inserting the third pilot frequency and the fourth pilot frequency; wherein, the third pilot frequency is from the third pilot frequency of the opposite end transmission signal position insertion, the fourth pilot is inserted from the fourth position of the signal transmitted by the opposite end, the third position and the fourth position are separated by a second preset time length, and the first pilot and the fourth pilot are orthogonal, the second The second pilot and the third pilot are orthogonal; the local receiver analyzes the signal transmitted by the local terminal and the signal transmitted by the opposite terminal.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to an information processing method and device. Background technique [0002] At present, with the continuous development of microwave technology in the communication field, microwave technology will develop from the existing FDD (Frequency Division Duplexing, frequency division full duplex) system to the IFD (Intra-frequency Full Duplex, same frequency full duplex) system . The meaning of frequency-division full-duplex system is: a system involving microwave technology, which uses different frequencies for sending and receiving when sending and receiving signals. The meaning of the same-frequency full-duplex system is: a system involving microwave technology, which uses the same frequency for sending and receiving when sending and receiving signals. Of course, the effect of using the IFD system is better than that of the FDD system, which can increase the bandwid...
