Project 12.1 — QPSK Modem Final Project

Goal

Build and document a QPSK transmit/receive chain with synchronization and quantitative metrics.

Required chain

flowchart LR
    BITS[Bits] --> QPSK[QPSK mapper]
    QPSK --> CH[Channel / impairments]
    CH --> SYNC[CFO / phase / timing correction]
    SYNC --> DEC[Decisions]
    DEC --> METRICS[EVM / BER]

Minimum deliverables

• signal model;
• impairment model;
• synchronization stages;
• constellation before/after;
• EVM and BER;
• final report.

Success criteria

Criterion	Target
BER after synchronization	defined by student
EVM after synchronization	defined by student
Reproducible command	required
Metrics JSON	required

Report conclusion template
