The chair is co-funded by the NSERC, BC Hydro, TransAlta Utilities Co., and the University of Victoria. The prime objective is to carry out research on engineering aspects of interaction of electromagnetic fields (EMF) with living systems. These aspects include all areas of theoretical and experimental dosimetry of EMF and exposure assessment. The emphasis of the program has been on fields associated with power lines and electricity in general. However, significant research has also been accomplished in the radio frequency (RF) area related to wireless communication.","PeriodicalId":261988,"journal":{"name":"1999 IEEE MTT-S International Topical Symposium on Technologies for Wireless Applications (Cat.

The bit error rate performance has been simulated and measured, and the results are presented.","PeriodicalId":261988,"journal":{"name":"1999 IEEE MTT-S International Topical Symposium on Technologies for Wireless Applications (Cat.

The method gives each station freedom to choose its own channel even when they can not all communicate with each other, and it also permits message routing between stations. This features allow a wireless LAN to operate in environments that have many obstacles, making it very suitable for IR networks, while multiplying the throughput by balancing the traffic over the available channels. The method is described in general terms, and simulation based results are shown.","PeriodicalId":261988,"journal":{"name":"1999 IEEE MTT-S International Topical Symposium on Technologies for Wireless Applications (Cat.

The simulator achieves its computational efficiency by adopting a simplified CDMA system model without compromising much of its practicality. Additional reduction in the computational complexity is obtained by implementing bit level operations for certain receiver tasks. Improved processing algorithms are also introduced, which further facilitates the simulation process. The rationale behind the development of the simulator as well as many techniques involved could prove beneficial to a CDMA receiver designer in terms of shortening the design cycle and reducing the computational power requirements.","PeriodicalId":261988,"journal":{"name":"1999 IEEE MTT-S International Topical Symposium on Technologies for Wireless Applications (Cat.

These MMICs and modules are designed for popular commercial digital radio frequency band from 18 GHz through 43 GHz. Commercial markets demand low cost and high performance. The best way to meet the present and future requirements is to use MMICs exclusively and use automated mass production method. TRW is actively addressing these issues by designing and fabricating high performance HEMT and HBT MMICs and by devising new packaging and assembly methods to enhance the performance and reduce the cost at the same time. TRW is now providing a complete set of MMIC chips to realize high performance receiver modules and high power transmitter modules.","PeriodicalId":261988,"journal":{"name":"1999 IEEE MTT-S International Topical Symposium on Technologies for Wireless Applications (Cat.
