Due to increase of data browsing and downloading using 3G enabled mobile handset, it is often required handover mechanism from Universal Mobile Tele-communication System (UMTS) to UMTS, Long Term Evolution (LTE) or Global system for Mobile Communications (GSM) while the handset is continuously transmitting and receiving data from the connected Node-B in a high speed motion. In UMTS, the handhel...

Indian mobile handset industry has seen explosive growth backed by liberalization and heavy investment in the telecommunication infrastructure. With growth it becomes extremely important for mobile handset brands to position their brands properly. This paper attempts to know how customers perceive different brands of mobile handset in the light of attributes considered by consumers in making pu...

Unseen handset mismatch is the major source of performance degradation for speaker recognition in telecommunication environment since handset distortions are tightly coupled with speaker characteristics. In this paper, a soft-decision unseen handset characteristics estimation method based on a priori knowledge interpolation is proposed to decouple the characteristics of the unseen handset and s...

This paper proposes a dynamic digital channel filtering method based on wavelet packet algorithm to realize a simplified and efficient multi-mode & multi-service software radio receiver which can provide the functions of several systems as well as several services simultaneously via one handset. The method can extract several different bandwidth signals adaptively, for the change of service bei...

Co-band multiple-antenna implementation in compact user terminals is necessary for harvesting the full potential of diversity and multiple-input multipleoutput (MIMO) technology in cellular communication systems. The recent worldwide deployment of Long Term Evolution (LTE), which requires the use of MIMO technology in the downlink, adds to the urgency of achieving both practical and optimal mul...
