Abstract
A first wireless communication apparatus includes a transceiver including a direct current (DC) component filter configured to remove a DC component of a first data signal received from a second wireless communication apparatus via a channel and output a corresponding second data signal, and a measurement circuit configured to determine a target subcarrier set based on a carrier frequency offset with respect to the second data signal, and measure noise and a signal-to-noise ratio (SNR) of the second data signal using the target subcarrier set.
Claims20
A first wireless communication apparatus comprising:
- a transceiver including a direct current (DC) component filter configured to remove a DC component of a first data signal received from a second wireless communication apparatus via a channel and output a corresponding second data signal;
- and
- a measurement circuit configured to determine a target subcarrier set based at least in part on a carrier frequency offset with respect to the second data signal, and measure noise and a signal-to-noise ratio (SNR) of the second data signal by using the target subcarrier set.
A first wireless communication apparatus comprising:
- a transceiver including a direct current (DC) component filter configured to remove a DC component of a first data signal received from a second wireless communication apparatus via a channel and output a corresponding second data signal;
- and
- a measurement circuit configured to perform a measurement operation on the second data signal using a valid subcarrier set of subcarriers represented by index values, among subcarriers included in the second data signal, when a carrier frequency offset with respect to the second data signal exceeds a threshold.
An operating method of the first wireless communication apparatus, the operating method comprising:
- receiving a first data signal from a second wireless communication apparatus via a channel;
- generating a second data signal by removing a direct current (DC) component of the first data signal;
- determining a target subcarrier set based on a carrier frequency offset with respect to the second data signal;
- and
- measuring a signal-to-noise ratio (SNR) and noise using the target subcarrier set.
