Problems solved by technology

However, when the modulation order cannot be divisible by 8, for example, when the modulation order is 6, it is difficult to complete the reading process of the data to be modulated by using a single command at this time.
Therefore, in the case that the modulation order cannot be divisible by 8, the modulation processing method in the prior art cannot conveniently and quickly complete the reading processing of the data to be modulated

Abstract

The invention discloses a modulation processing device and method. The modulation processing device comprises an external caching module which is used for storing to-be-modulated original data, a bytereading module which is used for reading to-be-processed data from the original data stored in the external caching module according to a preset bit, a byte shift module which is used for performingshift processing on the to-be-processed data according to the modulation order to obtain intermediate processing data, a byte bitwise AND logic operation module which is used for performing bitwise AND operation on the intermediate processing data and a preset constant to obtain to-be-modulated data, and a query module which is used for querying the corresponding complex data according to the mapping table and the to-be-modulated data. According to the technical scheme, bit can be used as an operation unit for modulation processing, and bit-level reading processing of to-be-modulated data is effectively achieved, and complex number data corresponding to the to-be-modulated data are inquired in combination with the mapping table, and the inquiry efficiency of the complex number data is effectively improved, and the modulation processing efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a modulation processing device and method. Background technique [0002] Based on the communication protocol, modulation essentially maps every continuous bit in the binary data to a complex number data, where the continuous number of bits is called the modulation order. For example, in QPSK (Quadrature Phase Shift Keying, Quadrature PhaseShift Keying) modulation, every continuous 2 bits in binary data are mapped to a complex number data, and its modulation order is 2; in 64QAM (phase quadrature amplitude modulation , Quadrature Amplitude Modulation) modulation, each continuous 6 bits in the binary data is mapped to a complex number data, and its modulation order is 6. [0003] According to the communication protocol, the current typical modulation orders are 1, 2, 4, 6, 8, etc., while most of the assembly instruction sets of existing processors use bytes as the operation unit...
