We give a direct proof of a cancellation formula raised by Han and Zhang (2004) on the level of differential forms. We also obtain more cancellation formulas for even dimensional Riemannian manifolds with a complex line bundle involved. Relations among these cancellation formulas are discussed.

In this paper, we present the results of the Acoustic Event Detection (AED) and Classification (AEC) evaluations carried out in February 2006 by the three participant partners from the CHIL project. The primary evaluation task was AED of the testing portions of the isolated sound databases and seminar recordings produced in CHIL. Additionally, a secondary AEC evaluation task was designed using ...

Multi input multi output system (MIMO) has become a viable option to meet the demand of high data rate wireless communication. But MIMO system performance is severely affected by the presence of co-channel interference (CCI). CCI cancellation in MIMO channel therefore is a challenging area of research. This paper provides a Kalman Filter based CCI cancellation approach which is connected to pha...

In this paper, a new selective and adaptive parallel interference cancellation technique is presented for code division multiple access systems. The proposed technique performs a parallel interference cancellation in multistage, and the computational complexity is reduced by applying the cancellation to unreliable signals only. The performance of the proposed scheme is investigated through comp...

In this paper, Selective Adaptive Parallel Interference Cancellation (SA-PIC) technique is presented for Multicarrier Direct Sequence Code Division Multiple Access (MC DS-CDMA) scheme. The motivation of using SA-PIC is that it gives high performance and at the same time, reduces the computational complexity required to perform interference cancellation. An upper bound expression of the bit erro...

The potential capacity gains of coordinated processing in the reverse link of a cellular system are evaluated. Three different matched filter-based receiver schemes, successive intra-cell interference cancellation, successive intraand intercell interference cancellation, and centralized successive interference cancellation, are analyzed considering different path loss exponents and various limi...

The existing mobile communication system suffer from problems like frequency selective fading and multi-path signals, multiple access interference due to imperfect nonorthogonal codes and narrow band interference due to coexisting systems. Multi-carrier Code Division Multiple Access (MC-CDMA) technique can combat these problems efficiently owing to its inherent properties. The objective of this...

In hospitals, surgeries are treated either on an outpatient or inpatient basis. Outpatients normally routine patients that enter and leave the hospital same day, while inpatients who need more complex have to stay overnight. More recently, a shift from surgery is occurring due scientific progress in anaesthesia surgical techniques. Identifying possible similarities differences between schedulin...

Crosstalk in DSL leads to significant performance degradation and large loses in data-rate. Several crosstalk cancellation techniques have been proposed to address this problem, however, in the existing literature the analysis of these approaches is based on SNR calculations and the SNR-gap approximation. Furthermore, for crosstalk cancellation techniques based on decisionfeedback, the effect o...
