Transmissions over radio may suffer interference both from out-of-band and in-band transmissions. Your task is to choose modulation schemes and develop models for interference for them, both within the same modulation scheme and across schemes. Target metrics focus on the demodulated signal and thus the disturbance that interferences cause in the demodulator: effects on the spectral content, noise floor, transmitter/receiver synchronization, etc. You evaluate your models both in theory and in practice, i.e. mathematically and through an implementation in GNU Radio.
