Abstract: In a wireless communications system using Orthogonal Frequency Division Multiplex technology, changing the nature of the signals being transmitted/received may be used to reduce power consumption. In one embodiment, reducing the number of carriers that are being employed may be used to decrease power consumption by permitting a reduced clock rate for driving some of the circuitry. Similarly, increasing the duration of the symbols used to encode the data may be used to reduce the clock rate. Other power savings may be found by using single-rail processing, allowing some of the signal processing circuitry to simply be shut down.

Abstract: Provided is a burst mode optical receiver capable of accurately detecting an optical signal of minimum amplitude, by automatically controlling a gain of a pre-amplifier according to an amplitude of an input optical signal. The burst mode optical receiver can automatically control a gain of a pre-amplifier according to the amplitude of an input optical signal using an output signal of a first peak detector. In other words, when the input optical signal has a small amplitude that meets the receiving sensitivity of the burst mode optical receiver, the gain of the pre-amplifier automatically increases, thereby improving the receiving sensitivity of the burst mode optical receiver.
