Digital pulse position modulation (PPM) is a preferred modulation format for the ideal photon counting channel and optical intersateilite links. Here we examine its potential for the coherent optical fibre communications channel. We present a thoroug

Twelve healthy subjects completed an open single dose study to evaluate the effect of co-administration of cimetidine and ranitidine on the pharmacokinetics of cifenline. Each subject received a single 160 mg dose of cifenline alone, in combination w

In this paper we present experimental results for a digital pulse position modulation (PPM) system that uses a low-bandwidth receiver. It is shown that the performance of such a system is relatively independent of channel dispersion. Thus a simple lo

In this paper we present computer results at 1. 5zm comparing coherent n-ary PPM with coherent PCM. We show that for a given fibre bandwidth there is an optimum word size and this occurs when the equivocations attributed to the error sources in n-ary

Practical and theory results are presented for an optical (λ = 1.523 μm) digital PPM system using a suboptimum filtered Ge APD receiver. These original results show that an optimum coding level and APD gain exists for received FWHM Gaussian pulse w
