英語使用場景

The differential detection and coherent detection based on space-time block codes and their comparisons are studied.

Simulation results show that the signal-noise ratio (SNR) of coherent detection is lower than that of differential detection when bit error rate (BER) is same.

The differential detection technique of TWACS signal is presented to eliminate harmonic interference and increase the signal strength.

When BER and constellation are same, the SNRs of coherent detection and differential detection decrease with the increase of the number of transmit antennas and receive antennas .

These methods include interferometry, autocollimators, and differential detection based on the internal reflection effect.

For differential space-time block code with differential encoding matrix constructed from QAM symbols, a differential detection algorithm which avoids channel power estimation is proposed.
