A multi-channel sensing system and operating method thereof are disclosed. The multi-channel sensing system includes a transceiver, emitting electrodes, and a receiving electrode. The transceiver includes a spreading code generator and a modulator. The spreading code generator generates a non-orthogonal spreading code through an invertible matrix and then the modulator modulates a data signal to spreading signals according to the non-orthogonal spreading code. The emitting electrodes, corresponding to sensing channels respectively, emit the spreading signals at the same time to pass through corresponding sensing channels respectively, and the spreading signals are converted into coupled signals by capacitive coupling. The receiving electrode receives the coupled signals and generates a received signal according to the coupled signals.
