| Descripció: | This article presents an architecture for time-modulated arrays (TMA) using Walsh-Hadamard sequences (WH-TMA) for 6G applications. The technique improves Direction of Arrival (DOA) estimation, achieving precision up to one order of magnitude higher than conventional TMAs in the evaluated SNR range. The inherent orthogonality of WH sequences eliminates spectral overlap and reduces computational complexity by replacing Fourier transforms with simple correlation operations. Furthermore, the system reduces sampling requirements by 60%. These advantages position it as a promising technology for the sixth generation (6G). |
