Embodiment 1

[0142] In Embodiment 1 of the present invention, a method for constructing an M-sequence-based interleaving sequence will be introduced.

[0143] The M sequence (m sequence) is a basic PN (Pseudo-Noise, pseudo-noise) sequence used in a CDMA (Code Division Multiple Access) system, and is an abbreviation for the longest linear feedback shift register sequence. Pseudo-random sequences represented by M sequences have simple definitions, are easy to generate, and have good autocorrelation and cross-correlation properties, so they are widely used in various communication systems. Pseudo-random sequences can also be used to generate interleaved sequences. Taking M-sequence as an example, the generation method of interleaved sequences based on pseudo-random sequences and the generation methods of different interleaved sequences used to represent different users are introduced.

Embodiment 2

[0201] In the second embodiment, a method of constructing an interleaving sequence based on a Gold sequence and a generalized pseudo-random sequence will be introduced.

[0202] Embodiment 1 of the present invention provides a method for constructing an interleaved sequence based on a Gold sequence. The schematic flow chart of the method is as follows Figure 6 As shown, the following steps S601-S605 are included:

[0203] S601: When the preset length of the interleaved sequence to be constructed is a power of 2 length, use a power of 2 length equal to the preset length as the length of the pseudo-random sequence to be generated.

[0204] The method in this step is consistent with the specific method in step S401 above, and will not be repeated here.

[0205] S602: Determine a plurality of generator polynomials and a plurality of initial states of the shift register according to a power-of-two length equal to a preset length.

[0206] The inventors of the present invention h...

Embodiment 3

[0259] In the third embodiment, an information processing method based on pseudo-random binary sequence interleaving will be introduced.

[0260] The transmitter distributes the constructed interleaving sequence, or sequence information required to construct the interleaving sequence, to a plurality of receivers.

[0261] The transmitter processes the information sequence to be sent or received according to the allocated interleaving sequence, or a combination of a pseudo-random sequence and a digital random sequence, including:

[0262] According to the allocated interleaving sequence, or a combination of a pseudo-random sequence and a digital random sequence, the information sequence to be sent is interleaved and sent; and / or

[0263] Deinterleaving is performed on the received interleaved information sequence according to the allocated interleaving sequence or the combination of the pseudo-random sequence and the digital random sequence.

[0264] From the description in Em...

Abstract

An embodiment of the invention provides an interleaved sequence constructing method, an interleaving-based information processing method and a transceiver. The interleaved sequence constructing methodcomprises the steps of constructing a plurality of pseudo random sequences according to the preset length of a to-be-constructed interleaved sequence; for each constructed pseudo random sequence, constructing at least one corresponding numerical digit random sequence according to the numbers of more than two kinds of numerical values in the pseudo random sequence; and for each constructed pseudorandom sequence and the corresponding numerical bit random sequence, and constructing a corresponding interleaving sequence according to a mapping relation between the pseudo random sequence and the numerical digit random sequence so that a plurality of interleaving sequences are used as a multiple-access resource for distribution. According to the interleaved sequence constructing method, relatively low computation amount and relatively short time delay are realized in a construction mode of combining the interleaved sequence or pseudo random sequence and the numerical digit random sequence;the combination of the interleaved sequence, or the pseudo random sequence and the numerical digit random sequence is used as a multiple-access user identification, thereby facilitating distribution to the receiver at the user end and facilitating standardization.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular, the present invention relates to an interleaving sequence structure, an information processing method based on interleaving, a transmitter and a receiver. Background technique [0002] With the rapid development of the information industry, especially the growing demand from the mobile Internet and the Internet of Things (IoT, internet of things), it brings unprecedented challenges to future mobile communication technologies. For example, according to the report ITU-R M.[IMT.BEYOND 2020.TRAFFIC] of the International Telecommunication Union ITU, it can be predicted that by 2020, the growth of mobile traffic will increase by nearly 1,000 times compared to 2010 (4G era), and the number of user equipment connections will also increase. It will exceed 17 billion. As massive IoT devices gradually penetrate into mobile communication networks, the number of connected...
