Radio System Design

Part 1 – Non-coherent DSB AM Radio Create the following AWR System Diagram. Use the setting from before. The low pass filter (LPFB) has the parameters shown. Note DC=1.5. This is a basic non-coherent radio. The ABS and LPF are equivalent to a diode peak detector. The diode would rectify the signal and the capacitor […]

Part 1– QAM and PSK In this lab you will learn about the constellation and I and Q waveforms of Quadrature Amplitude Modulation (QAM) and Phase Shift Key (PSK). Create the schematic below. The bullet list contains the information about each block. Quick Tip: Mouse scroll wheel moves schematic up/down, Ctrl+mouse wheel moves in and […]

Part 1 – I/Q Imbalance Load the file QAM_w_Phase_Noise_&_Imbalance.emp. The System Diagram should look like the one below. Watch the video “QAM System Simulation with Imbalance and Noise” to understand how the block diagram works. Explore each block to see the settings – they are not listed explicitly in this document since you have the […]

Part 1 – Amplifier Characterization Load the file Lab 4 – Nonlinearity and Channel Capacity_student_start_v1.emp. Using the Project tab on the left, open the circuit schematic AMP1900 Systems Test. Note, this is a circuit design similar to SPICE you may have done in the past. It is a different schematic type than a System Diagram. […]
