A Study on Improvement of the Channel Efficiency of FH-SS Transceiver Based on DDS Technique
Gi-Rae Kim, Young-Kyu Choi · Journal of information and communication convergence engineering · 2008
A novel high channel efficiency transceiver based on a fast acquisition frequency synthesizer has been designed. The direct digital synthesis (DDS) technique is applied and a simple memory look-up table is incorporated to expedite channel acquisition. The technique simplifies the frequency control process in the transceiver and thus reduces the channel switching time. As a result, the channel efficiency is improved. The designed transceiver is ideal for frequency hopping mobile communication applications.
