2D Spatial Indexing for Generalized and Quadrature Spatial Modulation in PASS
Abanoub Kamel, Ibrahim Al-Nahhal
In this letter, three novel spatial modulation (SM) schemes specifically designed for pinching-antenna systems (PASS) are proposed, offering a flexible trade-off between bit error rate (BER) performance and decoder computational complexity. The proposed one-dimensional quadrature…
