Through this course design, I further deepen the understanding and mastery of the minimum binary phase shift keying (MSK) modulation and demodulation performance, at the same time, the theoretical knowledge learned in the classroom is used in practice. It enhances my ability in analog simulation, and lays a good foundation for future system development and communication system simulation.) Platform: |
