Icera Inc., a developer of soft modems for mobile broadband, has announced the availability of IceClear, the company's ‘interference-aware’ receiver technology. IceClear uses signal processing algorithms implemented in software to cancel the effect of interference from other cells. This enables user data rates up to three times as fast as before under impaired conditions and improved cell site network efficiency.
Interference-aware receiver technology has been known to achieve substantial user throughput and cell capacity gains for some time, but until now it has been expensive to implement. IceClear is implemented in software, so there is no additional silicon cost.
Mobile broadband typically degrades from the high rates achieved when the user is close to the base station to much lower data rates at the cell edge. In addition, data throughput is seriously limited at the cell edge due to interference from signals at the same frequency and similar strength transmitted by adjacent cell sites, which is called ‘dominant interference power’.
In tests under conditions where a dominant interfering cell limits user throughput to a few hundred kilobits per second, IceClear was shown to boost throughput by a factor of up to 3.6.
IceClear is included in the latest version of Icera's Adaptive Wireless soft modem, providing a significant enhancement for customers with what the company claims is already independently recognized as the industry's top-performing HSPA mobile broadband technology.
