It is shown that its structure consists of a combination of envelope, multiple differential, and coherent detectors. The outputs of each of these detectors are jointly processed by means of an algorithm. This algorithm is presented in a recursive form. The derivation of the new receiver is general enough to accommodate uncoded as well as coded (e.g. trellis-coded) schemes. Furthermore, reduced complexity, near-optimal versions of the algorithm are also presented. Performance evaluation results for a reduced-complexity trellis-coded QPSK (quadrature phase shift keying) system have demonstrated that the proposed receiver dramatically reduces the error floors caused by fading. At E/sub b//N/sub 0/=20 dB the new receiver structure results in bit error rate reductions of more than three orders of magnitude compared to a conventional Viterbi receiver, while being reasonably simple to implement.<<ETX>>","PeriodicalId":256305,"journal":{"name":"IEEE Global Telecommunications Conference, 1989, and Exhibition.

This emerging role for digital cross-connect systems (DCSs), wherein the operating company uses that equipment as vehicles for the operation, administration, and maintenance (OA&M) of private T1 networks, is described. It is noted that DCSs have only recently found acceptance as LEC (local exchange carrier) vehicles for intraLATA T1 resource management of private networks. These cross-connects are today deployed as small, dedicated units serving a single network, as partitioned fabrics providing a virtual service to several private networks, or as functional units within T1 multiplexers situated in central offices. The latter application can ultimately bring end users high functionality at reduced cost, while also providing direct gateways into public network services. This multiplexer approach points the way for an evolving seamless premises-to-network service, one in which a single protocol would interface a network management platform that directs OA&M functions to element managers that then interoperate with disparate communication equipment.<<ETX>>","PeriodicalId":256305,"journal":{"name":"IEEE Global Telecommunications Conference, 1989, and Exhibition.
