Embodiment 1

[0067] In the total IQ data to be sent, each IQ data contains 15 bits and 1 bit sign bit, so an IQ flag bit can be set before each 16-bit IQ data, and record the position of each 16-bit data in the original total IQ data. And the compression flag set here is 0. The total IQ data to be sent is divided into N data blocks, where each data block consists of m pieces of IQ data, and m is an integer greater than zero.

[0068] Figure 4 It is a schematic diagram of dividing and compressing IQ data into data blocks in Embodiment 1 of the present invention. After the IQ data to be sent is divided into K data blocks, for the first data block, the data structure of m IQ data in the data block is analyzed by a window function, and for each IQ data in the data block, from The highest bit begins to intercept the continuous 4-bit effective bit data of each IQ data, and obtains the sign bit (5 bits in total) of each IQ data. After that, the untruncated bits in each IQ data are deleted to ...

Embodiment 2

[0075] In the total IQ data to be sent, each IQ data contains 15 bits and 1 bit sign bit, so an IQ flag bit can be set before each 16-bit IQ data, and record the position of each 16-bit data in the original total IQ data. And the compression flag set here is 1. The total IQ data to be sent is divided into N data blocks, where each data block consists of m pieces of IQ data, and m is an integer greater than zero.

[0076] After the IQ data to be sent is divided into K data blocks, for the first data block, the data structure of m IQ data in the data block is analyzed by a window function, and for each IQ data in the data block, from The highest bit begins to intercept each IQ data continuous n 1 bit effective bit data and sign bit. Afterwards, the untruncated bits in each IQ data are deleted to obtain the compressed IQ data of the first data block.

[0077] For the second data block, analyze the data structure of m IQ data in the data block through the window function, and f...

Embodiment 3

[0082] In the total IQ data to be sent, each IQ data contains 15 bits and 1 bit sign bits, so an IQ flag can be set before each 16-bit IQ data, and record the position of each 16-bit data in the original total IQ data. And the compression flag set here is 0. The total IQ data to be sent is divided into N data blocks, where each data block consists of m pieces of IQ data, and m is an integer greater than zero. In addition, in this embodiment, the compression factors of 1 and 0 respectively define that 6 and 9 effective bits are reserved after compression.

[0083] Figure 5 It is a schematic diagram of dividing and compressing IQ data into data blocks in Embodiment 3 of the present invention. After the IQ data to be sent is divided into K data blocks, for the first data block, the data structure of m IQ data in the data block is analyzed by a window function, and for each IQ data in the data block, from The highest bit begins to intercept the continuous 9-bit effective data ...

Abstract

The invention provides a sending method, a receiving method, a sending system, a receiving system, a sending device and a receiving device for IQ (in-phase quadrature) data. The sending method for IQ data includes: IQ data to be sent are divided into a plurality of data blocks, each data block comprises a plurality of IQ data, continuous n effective bits are intercepted from the highest bit of each IQ data of each data block, compressibility factors are determined according to the intercepted effective bits, compressed IQ data formed by the compressibility factors, sign bits and the intercepted effective bits and are sent, and data size of the IQ data is reduced greatly since partial data of each IQ data are intercepted to be effective data and the compressed IQ data are formed. Therefore, hardware equipment need not be improved, the existing hardware equipment is directly used, and the transmission requirement for optical port rate can also be met.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to an in-phase quadrature signal (In-phase Quadrature, IQ) data sending and receiving method, system and device. Background technique [0002] Data compression includes lossy compression and lossless compression. Lossy compression refers to a technical method to reorganize data according to a certain algorithm to reduce data redundancy and storage space. Lossless compression refers to a technical method to reduce the amount of data to reduce storage space and improve its transmission, storage and processing efficiency without losing information. [0003] Lossy compression takes advantage of the fact that humans are not sensitive to certain frequency components in images or sound waves, allowing certain information to be lost during the compression process. Although the original data cannot be completely restored, the lost part has a greater impact on understandi...
