1.Micro-power ICS repeater is a micro-power wireless repeater with an output power of 100 milliwatts. In addition to all the functions of traditional ICS digital wireless repeater, the biggest advantages are: small size, light weight, highly integrated, simple and practical. Micro-power ICS repeater integrates diplex, low noise amplifier, frequency conversion, IF signal digital processing, power amplifier and MODEM monitoring modules in the same digital IF board. The transceiver antenna is built-in, close to both sides of the chassis, and has a good transceiver isolation, to meet the coverage requirements.

2.The micro-power ICS is designed in the same way as the traditional ICS digital radio repeater. The modules are integrated into an IF board, and the ICS processing mechanism is at its core. It is through digital processing that ICS processing captures and tracks the transmission characteristics of the external leakage path, which can be equivalent to an FIR filter, called mirror filter. The signal to be sent is fed into a mirror filter. Ideally, the mirror filter output is exactly the same as the external leakage signal in the received signal. In this way, the mirror filter output can be subtracted from the input signal, thus suppressing interference. Since the external leak environment is unknown and variable, the ICS repeater requires the mirror to first capture the transmission characteristics of the leak path in the feedback suppression calibration state, and to continuously track the external environment changes while working normally.
