ZTE Integrates Interference Cancellation into HSPA+ Product Roadmap

­China's ZTE has announced plans to integrate Uplink Interference Cancellation (ULIC) into its next-generation HSPA+ base stations product portfolio.

"Signal interference has been a challenge for mobile operators since the early days of cellular communications," said Mr. Zhang Jianguo, general manager of ZTE's UMTS products. "ZTE is working to develop breakthrough HSPA+ base stations that will largely mitigate interference using ULIC. This will free precious spectrum resources so that operators support more voice traffic, more bandwidth-intensive data services, and more opportunities to generate revenue," added Mr. Zhang.

ULIC technology delivers improved system capacity by eliminating interference between multiple uplink data streams from users who are simultaneously transmitting data over the air. The technology enables operators to significantly increase their UMTS voice and data throughput. Enabled by the increased level of integration possible in today's commercial chips, ULIC brings the performance of CDMA-based modems close to their theoretical limits. The design is scalable and supports cancellation for a large number of simultaneous users and transmissions on the uplink.
