Embodiment 1

[0082] As shown in Figure 5, the modulation module in the transmitter is located after the secondary interleaving module, wherein the secondary interleaving module is used to send the overall interleaved sequence to the modulation module; the modulation module is used to modulate the received sequence, And send out the modulated sequence.

[0083] Corresponding to the position of the modulation module, the demodulation module in the receiver is located before the de-secondary interleaving module, wherein the demodulation module is used to demodulate the received sequence and send the demodulated sequence to the de-secondary Secondary interleaving module.

[0084] Referring to Figure 6, the method for transmitting information corresponding to the transmitter structure shown in Figure 5 mainly includes the following steps:

[0085] Step 601: The transmitter encodes the information that enters itself and needs to be transmitted, and the encoded sequence includes information bits...

Embodiment 2

[0101] As shown in Figure 9, the modulation module is located between the channel interleaving module and the rate matching module, wherein the channel interleaving module is used to send the interleaved information sequence and check sequence to the modulation module; the modulation module is used for receiving The information sequence and the check sequence are modulated, and the modulated information sequence and check sequence are sent to the rate matching module.

[0102] The demodulation module is located between the de-rate matching module and the de-channel interleaving module, wherein the de-rate matching module is used to send the de-rate-matched information sequence and check sequence to the demodulation module; The information sequence and the check sequence are demodulated, and the demodulated information sequence and the check sequence are sent to the channel deinterleaving module.

[0103] Referring to Figure 10, the method for transmitting information correspon...

Embodiment 3

[0116] As shown in Figure 12, the modulation module is located between the rate matching module and the secondary interleaving module, wherein the rate matching module is used to send the rate-matched information sequence and check sequence to the modulation module; the modulation module is used to send the received The information sequence and check sequence are modulated, and the modulated information sequence and check sequence are sent to the secondary interleaving module.

[0117] The demodulation module is located between the de-secondary interleaving module and the de-rate matching module, wherein the de-secondary interleaving module is used to send the obtained information sequence and check sequence to the demodulation module; the demodulation module is used to process the received information Demodulate the sequence and check sequence, and send the demodulated information sequence and check sequence to the de-rate matching module.

[0118] Referring to Figure 13, the...

Abstract

This invention discloses a method for transmitting information including: the transmitting end codes information to be emitted, interlaces channels and matches rate, then interlaces the matched information sequence and check sequence integratedly and transmits them to the receiving end, which de-interlaces the integer of the sequence and then caries out de-rate match, de-channel interlace and decoding to resume the information sequence. This invention also provides a system for transmitting information including a transmitter and a receiver, in which, the transmitter includes a coding module, a channel interlacing module and a decoding module.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method and system for transmitting information. Background technique [0002] Since entering the 21st century, wireless communication technology is developing at an unprecedented speed. With the increase of users' demand for various real-time multimedia services and the rapid development of Internet technology, the future wireless communication technology will provide users with greater convenience at a higher information transmission rate. At the same time, research on the physical layer, the lowest layer of wireless communication, has also attracted more and more attention. For example, Qualcomm has proposed a series of physical layer technologies in the 802.20 protocol. [0003] Referring to the structural diagram of a physical layer transmitter and receiver shown in FIG. 1 , the transmitter generally includes at least an encoding module, a channel interleaving m...
