Complete LTE PHY reference architectures for UE and eNodeB applications
February 07, 2011 // Phil Ling
CEVA and mimoOn are offering a range of LTE reference architectures based on the CEVA-XC communication processor, designed for 4G solutions in mass market terminal and infrastructure devices. Additional wireless communication standards, such as WCDMA, HSPA+ and WiMAX, can are also supported through software upgrades.
The User Equipment (UE) reference architecture targets both LTE FDD and LTE TDD up to category-4 with ultra-low power consumption and silicon cost to meet the strict requirements of mobile devices. Furthermore, the solution can be easily scaled down to TDD mode only or lower LTE categories to offer an additional cost and power saving.
In 40nm LP process, the silicon area of a CEVA-XC based LTE UE can be as low as 4 x 4mm with a power consumption of less than 200mW for Cat-4 PHY system (20 MHz bandwidth, MIMO 2x2, 150 Mbit/sec). CEVA and mimoOn's UE solution, which is now in design with a leading wireless vendor, can be seen at CEVA's booth located at stand 1F33 in Hall 1 at Mobile World Congress from 14 to 17 February.
The scalable eNodeB reference architecture targets both LTE FDD and LTE TDD, supporting various end products ranging from residential and enterprise femtocells through to high-density picocells. This reference architecture is built around homogenous CEVA-XC processors requiring minimal hardwired logic, allowing easy processor load balancing, flexibility to support multiple wireless communication standards, and C-based software development. In addition, this architecture allows simple software migration from off-the-shelf wireless infrastructures DSP chips.
According to CEVA, seven of the world's top eight handset OEMs are shipping CEVA-powered baseband processors today, and its DSP technology powers one out of every three handsets worldwide.All news
