DIGITAL MULTI-CHANNEL REPROGRAMMABLE RECEPTION PATH

FIELD: digital signal processing is reception devices. ^ SUBSTANCE: digital reprogrammable reception path enables operations in different communication standards and consists of several channels. Every channel can be used as independent channel separated by frequency from the others. At the same time digital oscillator is intended for signal spectrum transfer from intermediate frequency to zero frequency; signal from oscillator output proceeds to decimation filter. Order of filter can be changed by disabling cascades of filters which implement decimation filter. Gain, which is set in gain-phase correction unit, depends on order and degree of filter and also on power spectral density of input signal. Availability of routers enables to connect any input to any decimation unit output. Routers have adders along with commutators in its structure and it enables to join any pair of channels. ^ EFFECT: creation of digital reprogrammable multi-standard receiver, which uses digital intermediate frequency and ensures high speed of signal processing with high functional flexibility and reliability. ^ 9 cl, 10 dwg
