IN-PHASE AND QUADRATURE DATA TRANSMISSION METHOD AND DEVICE

摘要

The embodiment of the present invention discloses an in-phase and quadrature (IQ) data transmission method, which includes that NSAM sampling points in a single antenna single carrier symbol block of IQ data to be transmitted are divided into p data blocks, each data block includes q sampling points; the common index part exp, the index function f(exp) and each mantissa part of the q sampling points in each data block are determined respectively; the common index part and each mantissa part of the q sampling points in each data block are mapped into the corresponding data blocks respectively; and the p data blocks are transmitted through common public radio interface CPRI frames. By using the embodiment of the present invention, the NSAM sampling points are divided into the p data blocks, each data block includes the q sampling points, after the q sampling points are determined as the common index part, the index function and the mantissa part, they are mapped into the data blocks, the bit width required by data transmission can be reduced, and the efficiency of data transmission is improved.
