Digital radio frequency (RF) receiver

摘要

A digital RF receiver does not use a separate receiver according to a mode and a band for multi-mode reception, MIMO reception, and bandwidth extension reception, and changes only setting variables in a single receiver structure so as to implement multi-mode reception, MIMO reception, bandwidth extension reception, and/or simultaneous multi-mode operation, such that complexity of the receiver, development cost, and power consumption can be reduced.

1. A digital RF receiver comprising:
an antenna unit configured to output a signal received at an antenna; a radio frequency (RF) unit configured to convert the received signal into a digital reception signal, and output the digital reception signal; and a digital front end (DFE) unit configured to perform a decimation process for the digital reception signal and remove an interference signal component of a contiguous band, wherein variables of an input sampling rate, a carrier frequency and a bandwidth are established in the RF unit, and wherein variables of an output sampling rate, a bandwidth, an inter frequency (IF), an integer decimation rate and a rational decimation rate are established in the DFE unit.
