Decoding order is an important issue for serial group interference cancellation (SGIC) algorithm. Different ordering schemes for SGIC are compared. While layers in SGIC suffer from unequal receive diversity, parallel group interference cancellation (PGIC) has the potential to achieve full receive diversity for all the layers. Performance of both the algorithms are analyzed and compared. Finally we show that the optimal performance of layered block codes could be achieved by sphere decoding (SD) which approaches the maximum likelihood detection performance with lower complexity.","PeriodicalId":324953,"journal":{"name":"IEEE SoutheastCon, 2004.

Designing applications for complex integrated circuits (IC) composed of tens of millions of transistors is the norm. These systems are composed of complex hardware modules integrated to create a System-On-Chip (SoCs) design. In today?s technology, Register Transfer Level (RTL) digital system designs and associated modeling of complex ICs have been based on two prominent hardware description language (HDLs)s known as VHDL and Verilog. However, a new arising HDL language being integrated in the design of these complex system is known as SystemC.

The aim is to reveal the harmonic behavior of the working flux in the air gap, which controls the performance, and the operational behavior of the whole machine. A permanent magnet motor is used to perform the analysis and study the effects. Its original design contains 6 rotor poles and 36 stator slots with three phase currents embedded. For the comparison purpose, the rotor is redesigned to have 4, 8, and 12 poles mounted on the same rotor iron surface and the excitation currents were rearranged so as to produce 4, 8, and 12 poles respectively without changing the stator structure. FEM analysis is adopted to obtain the working flux waveform, and the Fourier filter is used to extract its harmonic components. The result demonstrates that there are more harmonic components contained in the working flux as the number of slots per pole per phase decreases.","PeriodicalId":324953,"journal":{"name":"IEEE SoutheastCon, 2004.

Cyclic Redundancy Check (CRC) codes can be used as URL signatures. When a packet is received, CRCs are generated on the fly with the use of very simple hardware circuits. Existing network adapters are not programmed to generate CRCs on packet subfields. However, it is possible to use the CRC circuit of a network adapter to simultaneously generate the packet CRC and CRCs on any subfield (such as the URL string in the HTTP GET request header) of the packet. The intermediate CRC codes (available from the CRC circuit) can then be used to produce a URL signature for each incoming HTTP request and do URL routing table look-up. In this paper we evaluate alternatives for URL signature generation that rely on hardware or software computation of CRC32 codes. Our results indicate that the delay of producing the signature in software is smaller (100s of nanoseconds) as compared to the alternative of using the CRC circuit in existing adapters (10s of microseconds).","PeriodicalId":324953,"journal":{"name":"IEEE SoutheastCon, 2004.

Classroom modeling of networks is a technique to illustrate the theoretical aspects of networking through practical models of computer networks.
