A frequency tuning apparatus includes: a frequency tuner configured to tune an oscillation frequency of an oscillator based on target information extracted from a mapping table in correspondence to a target frequency, and oscillation information collected from the oscillator; and a frequency compensator configured to compensate for a compensation error between the tuned oscillation frequency and the target frequency based on an offset table.

Apparatus and method for tuning frequency

A receiver includes a low noise amplifier (LNA) configured to amplify an input RF signal using a first current supplied by a first current source, and a voltage controlled oscillator (VCO) for applying an oscillation frequency to the amplified signal by generating an oscillation signal using the first current.

Receiver and operating method thereof

An on-off keying (OOK) transmitter and communication method are provided. The OOK transmitter may include a data encoder configured to encode input data into a transmission sequence, a pulse shaper configured to generate pulses based on the transmission sequence, a bi-phase controller configured to generate a control signal to control a random change in phase, between two phases, of a carrier based on the transmission sequence, a bi-phased switch configured to randomly change a phase of the carrier generated by a voltage-controlled oscillator (VCO), based on the control signal, and a power amplifier (PA) configured to generate a transmission signal based on the generated pulses and the carrier with the randomly changed phase. The PA may be a bi-phasing PA, and the bi-phased switch may be included in the bi-phasing PA.
