GNSS_NEW GNSS软件接收机

GNSS软件接收机，源自《软件定义的GPS和伽利略接收机》书中配套程序，做过修改，在原有程序框架下使用了2阶锁频环辅助3阶锁相环

%function acqResults = acqNewThreshold（longSignalsettings）
%用37号星捕获结果的最大值当作门限的参考依据
%Initialization================================================
%程序开始的时间，用来计算捕获过程所用的时间
startTime=clock;

settings=initSettings（）;

samplesPerCode=round（settings.samplingFreq/...
                   （settings.codeFreqBasis/settings.codeLength））;


fid=fopen（settings.fileName‘rb‘）;
addpath include
addpath geoFunctions
longSignal=fread（fid11*samplesPerCodesettings.dataType）‘;
fclose（fid）;

                   
                   
signal1=longSignal（1:samplesPerCode）;
signal2=longSignal（samplesPerCode+1:2*samplesPerCode）;

signal0DC=longSignal-mean（longSignal）;

%Find sampling period
ts=1/settings.samplingFreq;

%Find phase points of the local carrier wave
phasePoints=（0:（samplesPe
