Abstract
Frequency Hopping system based on PDC system is examined. TDMA frame length of PDC system (half-rate) last 40[msec], which consist of 6 TDMA structure. PDC does not apply interleave among slots, or strong coding either. Antithetically, here, we define Frequency Hopping system whose TDMA frame is shorter than that of PDC, and which achieve interleave among slots, then evaluate the defined system. Additionally, strongly tied coding and highly accurate transmit power control is implemented to this system. In this paper, this system's simulation results both at link level, and system level is introduced. Even though there are some problems to realize this frequency hopping system, we have found that frequency hopping system has capability to achieve much higher capacity than existing system, in principle.
