We consider the design of biorthogonal, as opposed to orthonormal, discrete multitone (DMT) systems supporting multiple services in a single antennae setting. The services may have differing quality of service (QoS) requirements, quantified by bit rate and symbol error rate specifications. Different users on the system can be potentially assigned different(More)
We provide a complete characterization of discrete multitone transmission (DMT) systems that employ a cyclic prefix redundancy and that can be equalized by a bank of one-tap equalizers in each subchannel, for almost all values of channel parameters. We show that among all possible finite-impulse response transmitting and receiving filters of arbitrary(More)
Technology if left alone can’t evolve, merging of technologies leads to creation of a hybrid which paves the way for the future. This paper elaborates the convergence of a system which measures mechanical parameters and a telecommunication network. AIVA stands for Advanced Intelligent Vehicular Analytics which will record all the vehicular diagnostic data(More)
We consider optimal orthonormal filter banks for subband coding of wide sense cyclostationary signals, with N-periodic second order statistics. An M-channel uniform filter bank, with N-periodic analysis and synthesis filters, is used as the subband coder. Dynamic schemes involving N-periodic bit allocation are employed. An average variance condition is used(More)
This paper considers the design of biorthogonal DMT multicarrier transceiver systems supporting multiple services. The supported user services may have differing quality of service (QoS) requirements, quantified by bit rate and symbol error rate specifications. Our goal is to minimize the transmitted power given the QoS specifications for the different(More)
