One of the enabling technologies for this to happen is asynchronous transfer mode (ATM) networking. In addition, the exploding use of mobile terminals-laptop computers, personal digital assistants (PDAs) etc.-means there will be more demand to extend these multimedia-capable applications to the mobile terminal. This requires the extension of ATM technology to high-speed wireless communications (>20 Mbps). This is an active area of research around the world. This article describes the technical challenges posed by wireless ATM networking and gives an overview of wireless ATM efforts under way, focusing on specific research projects in the USA and Europe.","PeriodicalId":117877,"journal":{"name":"1996 IEEE International Conference on Personal Wireless Communications Proceedings and Exhibition.

The receiver based on this algorithm is tested experimentally in real time using a digital signal processor. Its performance is evaluated for a signal based on the North American cellular standard, transmitted over a Rayleigh flat fading channel. The test results show that the algorithm significantly reduces the irreducible error floor. Under adequate SNR conditions, this method of error correction is quite attractive compared to other techniques such as coding, insertion of pilot symbols, or the diversity method, because it requires no overhead bits. Also, since the algorithm does not require any modification to the frame structure of the signal, it may be preferred if the transmitting signal format has already been standardized.","PeriodicalId":117877,"journal":{"name":"1996 IEEE International Conference on Personal Wireless Communications Proceedings and Exhibition.

The user can initiate and receive calls on the basis of a unique, personal, network transparent personal telecommunications number across multiple networks, public and private, at any terminal, fixed or mobile, irrespective of geographic location. PCS usage is limited only by terminal and network capabilities and restrictions by the network provider. The entire service is highly personalised. The variety and the quality of services make PCS distinct from other telecom services. What distinguishes one PCS service provider from the other is the quality of the response that the users get each time they interact with the service provider's organisation. A good customer care and billing system (CCBS) is the key to providing such a high quality of response.","PeriodicalId":117877,"journal":{"name":"1996 IEEE International Conference on Personal Wireless Communications Proceedings and Exhibition.

Accounting here pertains to the collection and distribution of subscriber usage data which could be used for statistical or billing purposes. Addressing billing issues is beyond the scope of this paper. The CDPD standard has addressed a number of key issues arising in providing an accounting service for cellular networks which can be of interest to the entire cellular community. These include issues of inter-service provider visiting. Protocols for the exchange of accounting data between multiple service providers are also discussed. This paper highlights some of the key elements of the CDPD accounting architecture that can be adopted for specifying a generic architecture for cellular voice networks. Accounting support for virtual private networks within the framework of this architecture is also discussed.","PeriodicalId":117877,"journal":{"name":"1996 IEEE International Conference on Personal Wireless Communications Proceedings and Exhibition.

This results in the performance degradation of the angle of arrival estimation schemes in supplying the accurate look-direction information to the beamformer. An effective adaptive antenna scheme is devised to prevent the desired signal cancellation in the optimal weight vector computation of the beamformer without resorting to the derivative or other higher order constraints in the angular region of interest.","PeriodicalId":117877,"journal":{"name":"1996 IEEE International Conference on Personal Wireless Communications Proceedings and Exhibition.
