Provided is a mini integrated control device including a first control unit for receiving large-scale sensor data generated while an autonomous driving robot is operated and performing large-scale calculations in parallel, a second control unit for performing the large-scale calculations in parallel together with the first control unit, a micro control unit for monitoring a state of power of the robot, monitoring obstacles located near the robot, controlling a motor of the robot, controlling a relay module of the robot, and communicating with the first control unit, and a power supply for controlling supply of power.

Mini integrated control device

The present invention receives simultaneously RF signal of different frequency band and processes the RF signal received, at this time a BPS receiver minimizes aliasing generated by RF signal. The present invention comprises a sampling process unit which samples a signal summing a first RF signal and a second RF signal of different frequency bands with time gap, a quantization process unit which generates a first stream signal and a second stream signal from signals sampled by the sampling process unit according respective time information in the signal summing the first RF signal and the second RF signal and a signal process unit which performs FIR filtering with reference to phase shift for a respect frequency band of the first stream signal and the second stream signal, separates the first RF signal and the second RF signal based on a result of the performance.

BPS receiver

A receiving apparatus includes: RF filters for selecting and outputting a signal to be down-converted from among a plurality of received signals having different bands; a phase conversion unit for generating a phase difference between output signals of the filters and down-converting the output signals of the filters to output a plurality of sample signals; a quantization unit for converting the plurality of sample signals from discrete signals into digital signals; and a signal separation unit for separating and outputting each of a plurality of output signals corresponding to the plurality of received signals from the output signals of the quantization unit by using a phase shift value caused by the phase difference.

Receiving apparatus and receiving method

A digital direct conversion receiving apparatus, including: a phase conversion unit to down-convert a Radio Frequency (RF) signal into a plurality of sample signals, and generate a certain phase difference among the plurality of sample signals when the RF signal is down-converted; and a variable complex gain unit to remove an image component from the plurality of sample signals using the generated phase difference.
