[0020] The present invention will be further described below in conjunction with the drawings and specific embodiments.
[0021] figure 1 It is a block diagram of the electrical principle of a multi-dimensional dynamic interleaving device for multi-antenna scattering communication, which includes an adaptive code modulator, interleaver, spatial mapper, frequency conversion and amplifier, dynamic interleaving rule planner, multi-dimensional channel state feedback, Amplification and frequency converter, channel equalizer, de-interleaver, demodulation decoder, power supply and clock unit; among them,
[0022] Send information into the adaptive coding modulator, after completing adaptive error correction coding and QPSK or QAM modulation mapping, the modulated signal is sent to the interleaver; the interleaver reorders the modulated signals according to the interleaving matrix, and the reordered modulated signal enters Spatial mapper: According to the spatial mapping rules, the spatial...
