Signal processing apparatus and method
摘要
說明書
In the above-described manner, the reception apparatus 200 is able to receive and decode the transmission signal transmitted from the transmission apparatus 100. That is, the reception apparatus 200 is able to receive and accurately decode the transmission frame transmitted as a frame having a duration of 0.2 seconds or shorter, with the known synchronization pattern (SYNC) being distributed substantially evenly thereover, and thus obtain the weather observation data TM. The reception apparatus 200 is thus able to suppress the reduction in the reception sensitivity.
In other words, the reception apparatus 200 is able to accomplish transmission of a wireless signal over a longer distance while controlling an increase in power consumption of the whole apparatus. Accordingly, adoption of this reception apparatus 200 makes it easier to realize a system for transmitting the weather observation data obtained in the weather observation apparatus 31 installed, for example, at a place at which the observation of the weather data by man power is difficult, such as in a mountainous region, and at which a large-scale external power supply is not easily available, to, for example, an urban area near a base of a mountain or the like (e.g., to a research facility of a university or the like, or to a facility such as a data center or the like).
