Abstract(in English) | MWHCDM (modified Walsh-Hadamard code division multiplexing) is suitable for helicopter satellite communications, where rotor blades periodically block the transmission channel. However, its initial acquisition performance degrades due to the carrier frequency offset. This report proposes initial acquisition with improved tolerance of carrier frequency offset. The proposed scheme employs parallel processing of frequency-shifted received signals, an enhanced evaluation function, and recursive integration and achieves the expected performance. |
