The Assessment and Analysis of using a Temperature Sensor to Regulate the Automatic Gain Control of the Amplifier in a FLASH - OFDM System

This study emphasizes the simulation and analysis of the compensatory effect of temperature on automatic gain control (AGC). From the analytical results, a temperature regulation mechanism was proposed. The technology most appropriate for and adaptive to mobile terminal stations under various temperatures was considered to ensure excellent transfer quality of the mobile terminal station. Finally, the effectiveness of the proposed temperature-regulating AGC mechanism in regulating the output power and gain of low noise amplifiers (LNAs) was verified. This mitigated the effects of interference and improved the service quality during the transfer process. The temperature sensor for regulating AGC was then applied to mobile wireless transfer devices and integrated into fast low-latency access with seamless handoff-orthogonal frequency division multiplexing (FLASH-OFDM) wireless mobile network cards to assess and verify the expected effects. In the future, this mechanism can provide a reference for mobile device technologies such as worldwide interoperability for microwave access (WIMAX) and long-term evolution (LTE).
