In this work we analytically investigate optimal combiners for pre-amplified diversity receivers that operate under medium-tostrongatmosphericturbulence. We first demonstrate that the combi ner performance is strongly affected by the existence of a signal-amplified spontaneous emission beat noise at the output of the photodetector. Due to the Signac dependent nature of noise, the optimal combi ner can...
This paper outlines a review of application of ShuffleNet and its variations as logical topologies in lightwave networks and tries to consolidate the results reported so far. ShuffleNet, a very popular interconnection structure, proposed by Acampora as a logical topology in multihop optical networks has been generalized later with a view to obtaining a network topology for optimal throughput. Bilayered...
A hybrid pulse interval modulation code-division multiple-access (hPIM-CDMA) scheme employing the strict optical orthogonal code (SOCC) with unity and auto- and cross-correlation constraints for indoor optical wireless communications is proposed. In this paper, we analyse the symbol error rate (SER) and bit error rate (BER) of hPIM-CDMA. In the analysis, we consider multiple access interference (MAI),...
