Description:

ICS(Interference Cancellation System) ICS repeater adopts adaptive noise canceler and achieve the complete separation of signal and the interference by using the output of interference sources, best estimating the interference value and then to subtract the estimated interference value from the input with mixed interference through the cooperation/coordination of digital filter and the adaptive algorithm. The most important characteristic of adaptive filter is that it can effectively track the changing input signal in the unknown environment to optimize the output signal to the best. Then it reaches the purpose to cancel the interference signal, while in improving the gain of the system, it reduce the isolation requirement of the equipment and its performance and functions meet the conventional standard of wireless repeater.

 

The ICS Repeater (Interference Cancellation System) is a new kind of single-band RF repeater that can automatically detect and cancel the interference signals caused by oscillation of RF feedback between the Donor and Coverage Antennas in real time by adopting DSP (Digital Signal Processing) technology. It can continuously and stably cancel the interference signals and be adapted to any changes in the surrounding RF environment (including fixed and mobile objects).

Like the RF repeater, the ICS Repeater is working as a relay between the BTS and mobiles. It picks up the signal from the BTS via the Donor Antenna, linearly amplifies the signal and then retransmits it via the Coverage Antenna (or the Indoor Signal Distribution System) to the weak/blind coverage area. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.

The ICS Repeater is mainly applicable to such case:
· The repeater can find an installation place which can receive pure BTS signal at strong enough level and can meet the requirement of isolation to avoid self-oscillation;
· And the isolation requirement between the donor and coverage antennas is hard to meet by using a RF repeater.
·
In comparison with standard RFR (RF Repeater), FSR (frequency shift repeater) and FOR (fiber optic repeater), the ICS Repeater has the following benefits and disadvantages:

Advantages:
Easy to build the installation site;
Lower cost of equipment and site-building.
Lower maintenance cost (no expense for deteriorating fiber optic cable);
The Coverage Antenna can face to the same direction of the Donor Antenna (which can not be realized by RFR).

Disadvantages:
High signal noise may be introduced since the Donor Antenna picks up signal from the air;
The repeater shall be installed within the coverage of BTS.

Application:
To expand signal coverage or fill signal blind area where signal is weak or unavailable.
· Outdoor: Airports, tourism regions, golf courses, tunnels, factories, mining districts, villages, highways
· Indoor: Hotels, exhibition centers, basements, shopping malls, offices, parking lots.
