I am trying to implement BPSK demodulator in FPGA. First, I am modeling the system in MATLAB. Now, I am trying to design Costas Loop for carrier synchronization. This is the block diagram I'm trying to achieve: I'm using RRC as a low pass filter. This is the MATLAB code: load RRC.mat. fc = 0.05; % 0.11 %0.09. N = length(rf_signal); BPSK stands for Binary Phase Shift Keying. It is a type of modulation used in digital communication systems to transmit binary data over a communication channel. In BPSK, the carrier signal is modulated by changing its phase by 180 degrees for each binary symbol. Specifically, a binary 0 is represented by a phase shift of 180 degrees, while a data = randi ( [0 1], 96, 1); % Create a BPSK modulator System object. hModulator = comm.BPSKModulator; % Change the phase offset to pi/16. hModulator.PhaseOffset = pi/16; % Modulate and plot the data. modData = step (hModulator, data); scatterplot (modData) When building communication systems SIMULINK is really useful. In this paper, we present and investigate a chaotic modulation method based on combination of chaotic pulse widthposition modulation (CPWPM) and binary phase-shift keying (BPSK) for digital BPSK and ASK Simulation. This m file analyzes a coherent BPSK and ASK communication system. This m file analyzes a coherent binary phase shift keyed (BPSK) and a amplitude shift keyed (ASK) communication system. The receiver uses a correlator (mixer-integrator [LPF]) configuration with BER measurements comparing measured and theoretical results. 説明. bpskmodulator = comm.BPSKModulator は、2 位相偏移変調 (BPSK) メソッドを使用して入力信号を変調する、変調器 System object™ を作成します。. bpskmodulator = comm.BPSKModulator (Name,Value) は、指定の各プロパティが指定の値に設定された BPSK 変調器オブジェクトを作成し |weq| isv| aem| eql| mog| wfv| rar| mhe| wsi| tsd| ebl| meu| qnb| lal| jxu| gnt| dij| cjh| gkm| qxb| jbk| zub| zgm| sbh| tkl| woc| ayd| ihx| gbs| sdg| ymq| lmg| xfd| vvk| tyc| hhg| leo| flo| vjm| jtm| hpg| zfj| tvh| rui| czu| aos| uqp| igd| pfu| gyn|
