Description: WiMAX, or the IEEE 802.16 standard for broadband wireless access, is increasingly gaining in popularity as
a technology with significant market potential. This paper first provides an overview of the existing and
developing 802.16 standards and their key differences/applications. The PHY and MAC layers of a typical
WiMAX base station are then described. The associated implementation challenges faced by WiMAX
infrastructure developers, including performance/cost/flexibility trade-offs in the choice of silicon, are
clearly outlined. The paper then describes how FPGA-based system implementation can address these
challenges including the “accelerated time-to-market” requirement which is considered a key enabler for
early success in this market. As an example design, the physical layer implementation of the 802.16d
standard with Altera FPGAs and intellectual property (IP) is proposed. Platform: |

Description: Relaying and orthogonal frequency division multiple
access (OFDMA) are the accepted technologies for emerging
wireless communications standards. The activities in many
wireless standardization bodies and forums, for example IEEE
802.16 j/m and LTE-Advanced, attest to this fact. The availability
or lack thereof of efficient radio resource management (RRM)
could make or mar the opportunities in these networks. This
paper therefore provides a comprehensive RRM algorithm for
OFDMA-based multi-cellular fixed relay networks in a way to
ensure fairness among users with minimal impact on the network
throughput (in contrast, pure opportunistic RRM techniques
always favor users with good channel conditions Platform: |

Description: Cyclic Redundancy Check (CRC) is an error-checking code that is widely used in data
communication systems and other serial data transmission systems. CRC is based on
polynomial manipulations using modulo arithmetic. Some of the common Cyclic Redundancy
Check standards are CRC-8, CRC-12, CRC-16, CRC-32, and CRC-CCIT. This application note
discusses the implementation of an IEEE 802.3 CRC in a Virtex™ device. The reference
design provided with this application note provides Verilog point solutions for CRC-8, CRC-12,
CRC-16, and CRC-32. The Perl script (crcgen.pl) used to generate this code is also
included. The script generates Verilog source for CRC circuitry of any width (8, 12, 16, 32), any
polynomial, and any data input width.-Cyclic Redundancy Check (CRC) is an error-checking code that is widely used in data communication systems and other serial data transmission systems.

Description: Orthogonal Frequency Division Multiplexing
(OFDM) has been adopted by most wireless and wired communication standards these include wireless Local Area Networks (LANs) HyperLan2, 802.11a, broadband wireless(802.16) and lately the 802.15.3c for millimetre wave communications. In parallel, Field-Programmable Gate Arrays (FPGAs) have become an alternative for the implementation of those standards, due to their increased capabilities (speed and resources). This work introduces the design and performance evaluation of an OFDM transceiver, implemented on a FPGA platform for applications on a wireless millimetre wave radio system, operating around 60GHz.-Orthogonal Frequency Division Multiplexing
