By replacing the Alamouti codebook with the NSTBC codebook, a non-full-rate complex field codebook with pairwise orthogonality in each column is designed, which solves the orthogonality problem when the dimension N>2, reduces the processing complexity of the receiver and the probability of detection errors, and is suitable for backscatter communication.

AI Technical Summary
Existing codebooks cannot balance orthogonality and modulation characteristics suitable for backscatter communication when the dimension N>2, leading to increased processing complexity at the receiver and deterioration of communication performance.
By using a non-full-rate complex domain orthogonal codebook, replacing the Alamouti codebook sub-blocks with NSTBC codebook sub-blocks, a pre-designed codebook with pairwise orthogonality in each column is created, reducing the rate requirement and the number of antenna load impedance types.
This ensures the orthogonality of the codebook, reduces the processing complexity at the receiver, decreases the probability of detection errors, and reduces antenna load complexity while maintaining diversity gain.
