Transmission channel estimating process for wireless network, involves transmitting different driving sequences by transmission antennas, where driving sequences are predetermined from certain lines of Hadamard matrix
Transmission channel estimating process for wireless network, involves transmitting different driving sequences by transmission antennas, where driving sequences are predetermined from certain lines of Hadamard matrix
The process involves transmitting different driving sequences (S2-S4) by transmission antennas (6-9), where the driving sequences are predetermined from certain lines of a Hadamard matrix of order 52. A normalized driving sequence (S1) is transmitted by modulating lines of a matrix, taking other driving sequences among the modulated lines, and introducing a zero to a central position. An independent claim is also included for a system for estimation of a transmission channel in a wireless network.
