Transmitter optimization for single carrier and multicarrier transceivers on crosstalk-impaired ISI channels
نویسنده
چکیده
Transmitt,er optimization techniques for maximizing the throughput of linear IS1 channels impaired by additive-Gaussian noise and crosstalk are presented. Transmitter ends of both single carrier and multicarrier transceiver structures are optimized subject to a fixed average input energy constraint. The effect of transmitter optimization on channel throughput is quantified by comparison with scenarios where both the desired user and the crosstalker use a flat energy distribution across the transmission bandwidth.

1 Discrete Wavelet Multitone Modulation for ADSL & Equalization Techniques
The reliable delivery of information over severe fading wireless or wired channels is a major challenge in communication systems. At the heart of every communication system is the physical layer, consisting of a transmitter, a channel and a receiver. A transmitter maps the input digital information into a waveform suitable for transmission over the channel. The communication channel distorts th...

In this paper, we present the analysis of the multicarrier transmission based on peak-to-average power ratio reduction techniques based on Signal distortion technique. Multiplexing a serial data symbol stream into a large number of orthogonal sub-channels makes the multicarrier signals spectral bandwidth efficient. The performance of multicarrier modulation system over frequency selective fadin...

In this paper we propose a new space diversity scheme for broadband PLC systems using orthogonal space-time block coding (OSTBC) transmission combined with single-carrier frequency-domain equalization (SC-FDE). To apply this diversity technique to PLC channels, we first propose a new technique for combining SC-FDE with OSTBCs applicable to all dispersive multipath channels impaired by impulsive...

A plethora of single-carrier and multi-carrier (MC) CDMA systems have been proposed recently to mitigate intersymbol interference (ISI) and eliminate multiuser interference (MUI). We present a unifying all-digital Generalized Multicarrier CDMA framework which enables us to describe existing CDMA schemes and to highlight thorny problems associated with them. To improve the bit error rate (BER) p...
