摘要

The present technology relates to a signal processing apparatus and method which are able to suppress a reduction in reception sensitivity. A reception signal is compressed so as to have a predetermined signal level or lower, and transmission data transmitted from a transmitter side and included in the reception signal compressed so as to have the signal level or lower is decoded. For example, an approximate replica signal reproducing large amplitude changes of the reception signal is generated, and the approximate replica signal is subtracted from the reception signal to compress the reception signal so as to have the signal level or lower. The present disclosure is applicable to, for example, a signal processing apparatus, a reception apparatus, a transmission/reception apparatus, a communication apparatus, an information processing apparatus, an electronic device, a computer, a program, a storage medium, a system, and so on.

Also note that, although it has been assumed in the foregoing description that the transmission apparatus 100 transmits the weather observation data, the information transmitted and received may have an arbitrary content, and is not limited to the weather observation data. For example, the transmission apparatus 100 may be configured to generate and transmit transmission information including information (i.e., sensor output) outputted from any of various types of sensors that, for example, detect or measure an arbitrary variable or the amount of change therein. Examples of the arbitrary variable include an image, light, luminosity, saturation, electricity, sound, vibration, acceleration, speed, angular velocity, force, temperature (not a temperature distribution), humidity, distance, area, volume, shape, flow rate, time, time period, magnetism, a chemical substance, and odor.

That is, an apparatus to which the present technology is applied may be used in a system used for any desired purpose, examples of which include three-dimensional shape measurement, space measurement, object observation, movement/deformation observation, biometric observation, authentication processing, monitoring, autofocus, imaging control, illumination control, tracking processing, input/output control, electronic device control, and actuator control. In other words, the present technology is applicable to any desired system.
