Abstract
An encoding modulation method and transmitter are described. The method includes: oversampling and noise-shaping received multi-bit data to obtain N bits of data; using the N bits of data as a lookup table address to obtain a PWM puke modulation signal; multiplexing synthetic orthogonal (IQ) complex data of the PWM pulse modulation signal to be real number signal data; and converting the multiplexed real number signal data to an analog signal for power amplification and output, N being an integer representing a smaller number of bits than the received multi-bit data.
