Xilinx at Mobile World Congress 2008

Xilinx, Inc. (Nasdaq: XLNX) will be attending the Mobile World Congress 2008 in Barcelona, Spain from February 11 through 14. Xilinx will unveil its latest portfolio of flexible hardware solutions for mobile phone base stations, supporting all major air interfaces, including 3GPP-LTE. In addition, it will highlight a new digital pre-distortion (DPD) capability that enables infrastructure vendors to achieve significant power reductions from the latest generation of power amplifiers.

Thursday, 9a.m. – 5p.m.

Xilinx Demonstrations (Hall 1 – Stand E47)

  • Multi-mode Radio Card
    This demonstration supports UMTS, 3GPP-LTE, TD-SCDMA and WiMAX, using the DSP resources of the FPGA to cost effectively implement the signal processing requirements of digital up conversion (DUC), digital down conversion (DDC), crest factor reduction (CFR) and digital pre-distortion (DPD). To minimise FPGA utilisation and therefore reduce capital expenditure (CAPEX), the DPD processing is partitioned between the DSP resources of the FPGA and a MicroBlaze(TM) soft processor. This is then used to linearise the latest LDMOS RF power device from Freescale Semiconductor, achieving power outputs in excess of 40 watts whilst maintaining spectral mask. Xilinx has tested the DPD design with a number of power amplifiers and has observed output efficiencies of up to 35 percent.
  • Baseband
    This baseband demonstration comprises a complete, high-throughput, 3GPP-LTE-compliant physical downlink shared channel (PDSCH), utilizing IP components, including an LTE turbo decoder, FFT/iFFT blocks with cyclic prefix insertion, rate matching and QAM mapper/demapper functions. Implemented using the latest VirtexTM-5 FPGA technology, the transmit and receive functions are connected by Ethernet to a host PC that sources and displays different video streams. A dual video stream arrangement is then used to demonstrate the capabilities of the >100Mbps net throughput performance of the 3GPP-LTE PHY, over a 10MHz frequency band.
