Single antenna interference cancellation

Single antenna interference cancellation (SAIC) is a promising technology to boost the capacity of GSM networks without any needed change in the network.

It is very much in the interest of the network operator to use the allocated spectrum as efficiently as possible and to the highest possible capacity because most of the investment is done to get the licence for it. It would be desirable to have the frequency reuse of one, which means that each cell can operate in the same frequency. This in turn creates interference to the users operating in nearby places. Increase Interference causes voice quality to drop and may cause call drop. It is now a well known fact that it is possible to cancel the interference at the mobile handset side by changing the baseband software without changing anything in the network side. SAIC-enabled mobiles can work in high interference levels. SAIC-enabled mobiles need even less transmit power from the network which in turn reduces the interference in the network. Studies shows that the speech quality gain can be about 6% at a SAIC mobiles penetration of 10%, about 37% at a SAIC mobiles penetration of 50%, about 99% at a SAIC mobiles penetration of 100%.
