    Abstract: A method of saving power of a station in wireless network is provided. The station comprises a connectivity module, a central processing unit, and peripheral devices. The method includes: upon receiving a wake-up signal, powering on the connectivity module, the central processing unit, and the peripheral devices; performing the central processing unit and the peripheral devices in a connection state; performing the connectivity module in an authenticated state; and upon a condition that there is no data to be transferred to the station or after the station transmits and receives all needed data, performing a sleep mode to power off the connectivity module, the central processing unit, and the peripheral devices.

    Abstract: A communication system and an IoT system are provided. The IoT system is applicable to a wireless network system including an access point. The IoT system includes a WiFi module and a GPIO device. The WiFi module is configured to connect to the access point. The GPIO device is configured to provide a plurality of wake-up signals to the WiFi module through a GPIO pin. A predetermined time period between any two of wake-up signals is greater than an interval between two delivery traffic indication messages from the access point. The WiFi module includes a timer and a power management unit, the power management unit drains power to transfer the WiFi module from a sleep mode to a normal mode after the timer receives the wake-up signal.

    Abstract: An apparatus for receiving signals in a radio frequency system includes a low noise amplifier that amplifies and filters a signal received from an antenna; a first frequency mixer that mixes the signal output from the low noise amplifier and an oscillation signal supplied from a local oscillator to create a signal of an intermediate frequency; a second frequency mixer that mixes the signal of an intermediate frequency and one or more oscillation signals that have an offset added to have different frequency channels, which have a predetermined bandwidth, to create one or more signals of a baseband frequency; a channel selection filter that divides one or more signals generated in the second frequency mixer into one or more different frequency channels having a predetermined bandwidth using the offset; and an amplifier that amplifies the signals that have been filtered in the channel selection filter.

    Abstract: Disclosed is a method for adjusting FFT window of OFDM system. The method is categorized two scenarios when the maximum delay length of the channel is shorter than the guard interval length and when the maximum delay length of the channel is longer than the guard interval length. In respective scenarios, the method comprises steps: Step A, multiplying the guard interval (A1) damaged due to the path fading channel delay by a weighted value (α); Step B, multiplying the guard interval (A2) not damaged due to the path fading channel delay by a weighted value (1-α); and Step C, Adding the guard intervals of Step A and Step B together (A3) to be inputted into FFT; minimizing the inter-symbol interference, the inter-channel interference and the noise.
