SOLiD New-Interference Cancellation Repeater (SICR)
Product Specifications
SOLiD Interference Cancellation Repeater (SICR) is a digitalized on-channel RF repeater specially designed to provide a stable outdoor coverage enhancement by eliminating feedback signals. Interference between antennas such as fast-fading echoes caused by fast-moving vehicles is effectively cancelled in real-time to prevent oscillations.
SICR is the latest release in WCDMA ICS. By incorporating state-of-the-art digital signal processing and amplifier technologies, SOLiD N-ICS is companys commitment to the industrys requirement of Lighter, Smaller & Low Power product. It provides industry-lowest power consumption in the smallest form factor. The form factor of N-ICS is paralleled to competitions low power product having one-quarter power of N-ICS and allows one-man-lift.

2. System Block Diagram
SOLiD N-ICS system block diagram and the functionalities of each block are described in this section.
SOLiD N-ICS consists of five key blocks of Downlink RF path, Uplink RF path, Power Supply, ICM (Interference Cancellation Module) and modem for wireless remote management as shown in Fig.2. These blocks are designed with state-of-the-art technologies to provide the best quality and performance.
Donor and Service antenna port is for connecting Donor and Service antenna and is specially designed to secure proper level of isolation to allow maximum gain and output power. Donor & Service antenna in this block diagram is for demonstration purpose only and is not actually included in product package.
Donor and Service Duplexer is a filter that separates signal from each antenna into downlink and uplink path for bidirectional operation. It also combines uplink and downlink signals to be transmitted through antennas.

Up/Downlink LNA is the low noise amplifier at the first stage of each link which usually is integrated into the down converter module. Up/Downlink Converter Module is shown as DL_DN, DL_UP, UL_DN and UL_UP performs frequency conversion between Radio Frequency (RF) and Intermediate Frequency (IF) signals. IF signal is required for digital processing for interference cancellation.
Fig.2. N-ICS Block Diagram
Interference Cancellation Model (ICM) has three sub-blocks of Analog to Digital Converter (ADC), Digital to Analog Converter (DAC) and Interference Cancellation Logic. Downlink and uplink has its own DAC & ADC respectively. ADC converts IF signal to IQ-baseband signal to extract phase and amplitude information of signal, while DAC revert digital IQ-baseband signal to IF signal which is free of interference. Interference Cancellation Logic Analyzes variation of amplitude & phase for feedback signals to perform interference signal cancellation.
Power Supply Unit performs AC to DC conversion to generate and distribute DC powers to each modules and components.
Ethernet and Local Monitoring Port provides interfaces for local craft and Ethernet for WEB GUI.
NCU Modem is wireless modem for remote management by communicating with OMC service in either GSM or UMTS network.
