Problems solved by technology

[0024] Using the negotiation method to transmit system parameters has the following disadvantages: because the negotiation process usually takes a long time, this method takes a long time to determine the parameters of the entire system; every time a parameter is changed, the negotiation process needs to be re-negotiated, which is very cumbersome. And it takes more time; in addition, because the system parameters need to be placed in the data block, it also takes up the resources of transmitting normal data
[0030] The frame header transmission method has the following disadvantages: because the system parameters are very important, in order

Example Embodiment

[0072] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following examples are used to further describe the present invention in detail.

[0073] As mentioned above, the communication system usually adopts a preamble signal before the data frame to assist the communication system to complete the synchronization process. Figure 7 A schematic diagram of the structure of the preamble signal and data frame is given. like Figure 7 As shown, the preamble signal may be shared by several data frames, or may be used by each data frame. The preamble signal generally adopts an autocorrelation signal with good autocorrelation that can provide accurate timing information. For example, the preamble signal can be a frame synchronization sequence, or a Barker code in the radar, or other autocorrelation. signal, which can provide accurate timing information.

Abstract

The invention discloses a method for sending a communication system parameter, comprising the steps of: selecting an autocorrelation signal corresponding to the communication system parameter as a leading signal; combining the leading signal and a data frame to form a signal frame; sending the signal frame. The invention also discloses a method for receiving the communication system parameter, comprising: receiving the signal frame, identifying the autocorrelation signal as the leading signal in the signal frame; reading corresponding communication system parameter from a parameter table according to the autocorrelation signal. The invention also discloses a device sending the communication system parameter, a device receiving the communication system parameter, and a system transmitting the communication system parameter. The invention transmits the communication system parameter with the leading signal without occupying a data frame or a data frame header, so that the invention reduces cost of system, and enhances utilization ratio of channel as well as transmission efficiency.

Description

technical field [0001] The present invention relates to the technical field of transmitting communication system parameters, especially a method for sending communication system parameters, a method for receiving communication system parameters, a device for sending communication system parameters, a device for receiving communication system parameters, and a system for transmitting communication system parameters. Background technique [0002] A general model of a communication system is figure 1 As shown, it is mainly divided into a sending end, a receiving end, and a channel for transmitting signals between the sending end and the receiving end. [0003] exist figure 1 In the model shown, the sending end mainly includes a source and a converter. The role of the source is to convert all possible messages into the original signal. The converter converts the original signals such as speech and images that cannot be directly transmitted by electromagnetic waves into electr...
