Abstract

The invention discloses a short data packet incoherent detection method and detector based on conjugate zero point modulation. The detection method includes steps: S1, based on the autocorrelation characteristic of the Huffman sequence, obtain the zeros of the autocorrelation polynomial of the Huffman sequence, and construct a zero point codebook; S2, map the binary information bit sequence to be sent to the zero point codebook , extract the polynomial coefficients with these zeros as roots and normalize them to generate a Huffman sequence to complete signal modulation; S3, reverse the order of the Huffman sequence and send it to a multipath fading channel for signal transmission; S4, convert the The received sequence received from the multipath fading channel is reverse-ordered, and then z transform; S5, will be z The transformed polynomial is zero detected, and the binary information bit sequence is decoded. The invention is suitable for incoherent detection of short data packets under unknown multipath channels.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and more specifically relates to a non-coherent detection method and detector for short data packets based on conjugate zero-point modulation. Background technique [0002] With the popularity of the fifth-generation mobile communication (5G) and the miniaturization and intelligence of terminal equipment, application scenarios such as unmanned driving, Internet of Vehicles, and machine-to-machine communication (M2M) have gradually entered people's field of vision. In the future, wireless communication will emerge. More high-speed connection applications between "people and things" and "things and things". One of the major challenges emerging technologies must address is supporting a large number of devices with diverse and even conflicting traffic types, including high-speed cellular links, device-to-device connections, and wireless links carrying short packets of sensor data. Fra...
