This paper describes a type-II adaptive hybrid FEC/ARQ protocol using turbo codes for both voice and data services.Recently, a powerful family of error correcting codes using parallelconcatenated convolutional codes is ...

In this paper we formulate mathematically and solve maximin and minimax detection problems for signals with power constraints. These problems arise whenever it is necessary to distinguish between a genuine signal and a ...

New detectors employing test statistics which are formed by passing pairs of consecutive observations through one-step memory nonlinearities g(x, y) and summing the resulting terms are introduced. Problems of discrimination ...

In this paper, we provide an accurate analysis of the performance of coherent dense wavelength-division multiple-access (WDMA) schemes introduced for use in high-capacity optical networks. In our analysis, the effects of ...

Adaptive arrays are a key technique for maximizing the capacity of wireless multimedia CDMA networks. In this paper, we present two approaches for blind adaptive weight control in CDMA environment which offer low implementation ...

This paper evaluated the distribution of channel holding time in a hybrid satellite and cellular communication system. The channel holding time is defined as the time duration between the instant that a channel is assigned ...

Schemes for quantization and fusion in multi-sensor systems used for discriminating between two sequences of dependent observations are introduced and analyzed. The observation sequences of each sensor under the two ...

Efficient policies are derived for admitting voice and data traffic into networks of low-earth-orbit (LEO) satellites using code-division multiple-access (CDMA) with direct-sequence spread- spectrum (DS/SS) signaling. The ...

In this paper, perceptron neural networks are applied to the problem of discriminating between two classes of radar returns. The perceptron neural networks are used as nonlinearities in two threshold sequential discriminators ...

In this paper we provide an accurate analysis of the performance of a random-carrier (RC) code-division multiple-access (CDMA) scheme recently introduced for use in high-capacity optical networks. According to this scheme ...
