Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0023] Such as figure 1 As shown, the information modulation method based on data packets disclosed in the present invention includes the following steps:

[0024] Step 1: Divide the binary digital information to be transmitted into data groups with multiple bits as the unit;

[0025] Step 2: divide the data group with multiple bit units into two parts, the first part is the waveform selection status bit, and the second part is the time slot position status bit;

[0026] Step 3: Divide the symbol time into multiple time slots of the same size. The duration of the signal transmission waveform is one time slot, and no signal is transmitted in other time slots. The time slot position of the transmission waveform is determined by the time slot position status in the data group ...

Abstract

The invention discloses an information modulation method based on data packets. This method divides the binary digital information to be transmitted into a data group with multiple bits as the unit, and divides the data group into two parts, the first part is the waveform selection state bit, and the second part is the time slot position state bit; the code The meta-time is divided into multiple time slots of the same size. The signal transmission waveform lasts for one time slot, and other time slots do not transmit signals. The transmission waveform mapping rule and the time slot position mapping rule are formulated; according to the mapping rule, the The state of the divided waveform selects the state bit to select the shape of the transmission waveform, and determines the time slot position of the transmission waveform in the symbol time according to the state of the divided time slot position state bit in the data group to form a transmission signal. The invention improves the power efficiency of the modulated signal and improves the anti-interference ability of the signal.

Description

technical field [0001] The invention relates to an information modulation method in radio communication, in particular to an information modulation method based on data packets. Background technique [0002] Modulation is to match the characteristics of the transmitted signal with the characteristics of the channel, and transform it into a signal form suitable for effective channel transmission through modulation. For wireless communication systems, due to the openness of the space channel, the transmitted information will inevitably be affected by the channel environment and interference factors, resulting in errors and reducing the reliability of information transmission. In order to improve the anti-interference ability of the modulated signal, it is very critical which modulation method is used. Anti-jamming modulation technology is a modulation theory and technology different from conventional communication systems proposed around improving the reliability of informati...
