The book "Big Talk Wireless Communication" is a classic
Source and input conversion processing: analog signal, sampling [Nyquist theorem], quantization [uniform and non-uniform], data signal
Coding: source coding, joint coding, data signal -> bit stream
Modulation: sampling->quantization->source coding->channel coding->bit stream, using the amplitude A, frequency f, phase p, modulation, ASK, FSK, PSK of the sine stream
Channel: channel capacity [bandwidth, data rate, noise, bit error rate], wireless shutdown fading [large-scale effect, small-scale effect]
Channel multiplexing: space division multiplexing, frequency division multiplexing, time division multiplexing
