IN-PHASE AND QUADRATURE DATA TRANSMISSION METHOD

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 exponent part exp, the exponent function f(exp) and respective mantissa part of q sampling points in each data block are determined respectively; the common exponent part and respective mantissa part of q sampling points in each data block are mapped into the corresponding data blocks respectively; and p data blocks are transmitted by a common public radio interface CPRI frame. By using the embodiment of the present invention, NSAM sampling points are divided into p data blocks, each data block includes q sampling points, after q sampling points are determined to be the common exponent part, the exponent function and the mantissa part, they are mapped into the data blocks, the bit width required for data transmission can be reduced, and the efficiency of data transmission is improved.
