Abstract.
Receiver based on single-bit multi-target frequency measurement, the
finding algorithm frequency measurement performance in different
circumstances (such as the number of data bits, the number of samples, etc.),
by constructing a simulation system, a large number of simulation and
performance analysis. The different measured to the accuracy of the system and
finding a large number of simulation and performance analysis. The final
single-bit receiver by studying the practical application of the project is given
reasonable suggestions given to improve the measurement accuracy
improvement measures.

Introduction
Matlab simulink to build the receiver simulation system of single-bit, compare single-
bit receiver frequency measurement of the difference in performance of the receiver,
seeking single-bit receiver frequency receiver in combination with other
measurements to compensate for their own lack of possibility also need construction
of the other frequency measurement receiver simulink simulation module, such as
building wideband digital channelized receiver, digital channel received orders bit
receiver frequency measurement system. To build simulink platform for simulation
analysis, simulation conditions: AD sampling frequency the 5GHz, instantaneous
bandwidth of 2GHz. ADC can adjust the number of output bits (e.g. 1bit, 2BIT and
3BIT), the DFT kernel functions of quantization bits, DFT conversion points, the
number of the input signal, the input signal to noise ratio, the threshold detector to the
threshold size, etc., in order to adopt a large number of simulation trials single-bit
receiver frequency measurement sensitivity and dynamic range, multi-target
frequency measurement processing and analysis, and by changing these parameters,
the analysis of the impact of the changes in these parameters on a single-bit frequency
measurement performance to optimize these parameters to identify improve
