We propose here a large homogeneous calorimeter as the next generation neutrino detector for ν factories and/or conventional ν beams. The active media is chosen to be water for obvious economical reasons. The Čerenkov light produced in water is sufficient to have good energy resolution, and the pattern recognition is realized by a modular water tank structure. Monte Carlo simulations demonstrat...

This article continues the discussion of multiuser detection. We first analyze the BER performance of a conventional detector. Starting with the results for 2 user case, we extend it the case of K users. We then define certain other performance measures which are simpler to calculate (than BER) and yet give a reasonable insight into the performance of multiuser detectors. Finally, we try to def...

Timing recovery is a crucial component in a magnetic recording channel detector. Conventional timing recovery techniques are sufficient only when operating at high signalto-noise ratio (SNR). However, iterative error-correction codes allow reliable operation at very low SNR, where conventional techniques fail. In this paper, we summarize the timing recovery schemes based on a per-survivor proce...

The algorithm and the results of a nonlinear detector using a machine learning technique called support vector machine (SVM) on an efficient modulation system with high data rate and low energy consumption is presented in this paper. Simulation results showed that the performance achieved by the SVM detector is comparable to that of a conventional threshold decision (TD) detector. The two detec...

A number of research groups have been investigating the use of dedicated breast computerized tomography (CT). Preliminary results have been encouraging, suggesting an improved visualization of masses on breast CT as compared to conventional mammography. Nonetheless, there are many challenges to overcome before breast CT can become a routine clinical reality. One potential improvement over curre...

We investigate a new robust multiuser signal detector for asynchronous code-division multiple-access uplink channels under delay mismatch. We first formulate a robust decorrelating detector by dividing each user into two virtual users with rectangular chip pulse shapes. To increase the system capacity, a multistage version of the robust decorrelating detector is derived, which can achieve capac...

A new packet-based, multiple access scheme for connectionless, uncoordinated random access is proposed using code-division multiple access (CDMA) as the physical access method, and exploiting the use of a multiuser detector at the receiver. The new method uses a novel packet format with a common header with identical spreading codes for all users and packets, and random spreading codes for the ...
