- Abstract
- This paper proposes a practical method for AGC (Automatic Gain Control) in HPI (High-speed Portable Internet) system. Downlink packets in this systems consist of preamble symbols for AGC, AFC (Automatic Frequency Control) and other purposes and data symbols for traffic transmission. In this paper we did compare theoretical BER performance with simulation one and produced optimum parameter for AGC in this system. The proposed AGC method utilizes the preamble and requires a small amount of hardware. The validity of the proposed method is verified by computer simulation and real implemention.
