In LTE/LTE-A uplink receiver, frequency domain equalizers (FDE) are adopted to achieve good performance. However, in multi-tap channels, the residual inter-symbol and inter-antenna interference still exist after FDE and degrade the performance. Conventional interference cancellation schemes can minimize this interference by using frequency domain interference cancellation. However, those scheme...

Revenue management (RM) enhances the revenues of a company by means of demand-management decisions. An RM system must take into account the possibility that a booking may be canceled, or that a booked customer may fail to show up at the time of service (no-show). We review the Passenger Name Record data mining based cancellation rate forecasting models proposed in the literature, which mainly a...

Crosstalk is a major problem inmodern DSL systems such as VDSL.Many crosstalk cancellation techniques have been proposed to helpmitigate crosstalk, but whilst they lead to impressive performance gains, their complexity grows with the square of the number of lines within a binder. In binder groups which can carry up to hundreds of lines, this complexity is outside the scope of current implementa...

Twenty-seven patients with right cerebral infarcts resulting in left-sided neglect in a line cancellation task were also tested for line cancellation when the lines were confined to the left half of sheets. All but one patient (whose neglect in the former condition was minimal) were still impaired in the latter condition, a finding that indicates that hyperattraction to test stimuli in the unne...

Full-duplex systems require very strong selfinterference cancellation in order to operate correctly and a significant part of the self-interference signal is due to non-linear effects created by various transceiver impairments. As such, linear cancellation alone is usually not sufficient and sophisticated non-linear cancellation algorithms have been proposed in the literature. In this work, we ...

Successive interference cancellation is a promising technique for increasing the capacity of uplink CDMA channels. In this paper, the technique is extended to a low-earth orbit satellite channel. Unlike terrestrial cellular channels, satellite channels typically have a limited multipath profile, but significant closed-loop power control error due to the round-trip delay incurred in communicatin...

Cancellation of clutter and multipath is an important problem in passive bistatic radars. Some important recent algorithms such as the ECA, the SCA and the ECA-B project the received signals onto a subspace orthogonal to both clutter and pre-detected target subspaces. In this paper, we generalize the SCA algorithm and propose a novel sequential algorithm for clutter and multipath cancellation i...

Recent wireless testbed implementations have proven that full-duplex communication is in fact possible and can outperform half-duplex systems. Many of these implementations modify existing halfduplex systems to operate in full-duplex. To realize the full potential of full-duplex, radios need to be designed with self-interference in mind. In our work, we use a novel patch antenna prototype in an...

In a CDMA system, the performance of channel matched filter receivers are limited by the presence of multi-user interference. Hence receivers must be capable of suppressing these interferences. Interference suppression or interference cancellation works by subtracting the interfering users from the received signal, thus allowing an improved error rate for the user of interest. In this paper a h...

We study the improvement technique for multistage parallel interference cancellation (PIC) DS-CDMA multiuser receivers, which cancel only a fraction of the estimated multiple access interference (MAl) at each receiver stage. This technique takes into account the fact that the MAl estimate, especially in the earlier stages, contains substantial error, and a relatively conservative strategy of us...
