It has been verified recently that single carrier cyclic prefixed (SC-CP) with frequency domain equalizer (FDE) is a promising system for mobile communication and robust channel estimation is needed to build the equalizer's weight. Conventional SC-CP wireless system uses training sequences that put in every packet to get the channel information. This increases the overhead of the system. Here we propose a new channel estimation technique by employing cyclic prefix (CP) to maintain both system performance and throughput for this SC wireless system, with 300 kHz bandwidth and 1.6 Mbps throughput. The CP, which is inserted between blocked data to avoid inter-block interference (IBI), can be viewed as a source of channel information. If we can estimate the transmitted CP by conventional way, we can continue to estimate the channel adaptively. The simulation results show that the proposed channel estimation technique can maintain the system performance and gives 14,9% higher throughput compared with the conventional one when the number of packet is increased.
