Data transmission with multiple transmit antennas |
| 摘要 |
A first matrix (A) is multiplied by a Hadamard matrix (H), using a Walsh-Hadam code, which produces a resulting matrix (T). Signals (T 1.1-T L,K) are fed to individual antennas (A1-n). The fourth antenna (A4(=Ak)) receives the fourth signal from the matrix. Data (MS1- MS(k-1)) is fed to various stations and to the first matrix.
