Wireless Baseband

Comprehensive Baseband Solutions Enable Highly Integrated High-Performance Wireless Heterogeneous Networks

The Xilinx baseband IP portfolio includes comprehensive technologies to address baseband requirements in the evolving wireless base station infrastructure such as small cell and Cloud-RAN. Designed for multiple 3G and 4G standards including WCDMA/HSPA+, WiMAX and LTE, Xilinx’s baseband IP and Solutions provide flexibility, scalability and programmability while enabling system integration to accelerate design productivity for different base station form factor requirements with reduced power dissipation and BOM cost.

The Xilinx baseband IP is designed to fully leverage inherent flexibility and programmability of FPGAs and system-on-a-chip (SoC) devices to provide highly customized solutions to address rapidly changing base station requirements for evolving heterogeneous networks. Combined with a comprehensive design environment and pre-validated reference designs, the baseband IP lets developers focus on product differentiation rather than complex physical-layer functions. Additionally, Xilinx Vivado® Design Suite lets designers leverage a C design methodology. The suite enables high-level IP specifications to be directly synthesized into VHDL and Verilog, accelerating time-to-integration compared to conventional HDL-based designs.

Xilinx FPGAs Enable Next Generation Cloud-RAN (C-RAN) Solutions

In C-RAN architectures, baseband, higher-layer, and backhaul processing are centralized in a single (typically indoor) basestation that provides very high levels of processing capacity. Remote radios are distributed to provide the required wireless coverage. Hundreds of remote radios can be associated with each basestation.

C-RANs reduce system costs by exploiting the efficiency that results from pooling and centralizing base station processing. C-RANs also increase deployment flexibility by using remote radio heads for macrocell-level coverage and extend coverage to areas that are under-served by a conventional macrocells. The C-RAN architecture can also exploit the use of commodity technologies, including generic processing platforms (GPPs), and standard interfaces. This reduces the reliance on custom wireless technologies such as ASSPs and SoCs, and enables a more open and cost-effective platform for base station applications.

Xilinx C-RAN Solutions

The highly scalable FPGA family enables baseband pools with high throughput, enabling equipment designers to improve connectivity switching for high-performance and power-efficient C-RAN basestations. Scalable Xilinx FPGAs also offer dynamic reconfiguration for new and enhanced feature sets to keep up with evolving wireless standards (LTE-Advanced and beyond).
