Abstract
A transmitter including radio-frequency (RF) chains. Each RF chain includes a power amplifier, a band-pass filter, and an antenna for transmitting an analog signal using a beamforming with an angle of departure (AOD) defined by phase shifts of the analog signals transmitted by the RF chains. A processor to determine digital signals for transmission from the RF chains. Wherein there is one-to-one correspondence between a digital signal and an RF chain. An encoder to encode the digital signals with binary codes to produce a set of encoded digital signals and to combine the encoded digital signals into a combined digital signal. A digital-to-analog converter to convert the combined digital signal into an analog domain to produce a combined analog signal. A decoder to decode, using the binary codes, the combined analog signal into a set of analog signals and to submit the analog signals into the corresponding RF chains.
