A high channel efficiency transceiver based on direct access frequency synthesis technique

A novel high channel efficiency transceiver based on a fast acquisition frequency synthesizer has been designed. The direct access frequency synthesis 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 proposed transceiver is ideal for frequency hopping mobile communication applications.
