A coder-decoder simultaneously processing a plurality of first analog signals with only one analog-to-digital converter is provided. In an exemplary embodiment, the coder-decoder comprises a multiple access modulator, the analog-to-digital converter, and a multiple access demodulator. The multiple access modulator combines the first analog signals according to a multiple access algorithm to obtain a first multiple access signal comprising the first analog signals. The analog-to-digital converter then converts the first multiple access signal from analog to digital to obtain a second multiple access signal. The multiple access demodulator then separates the second multiple access signal according to the multiple access algorithm to obtain a plurality of first digital signals respectively corresponding to the first analog signals.
