The ‘roaming’ attribute means that the customer could be found anywhere within the network, which in the case of several systems can ex

Optical Encoders and Decoders for OCDMA,te specifically. Radio coverage in a cell can be well defined; co-channel interference from adjacent cells can likewise be defined; analog voice with FM operates in an assured manner; signalling over the network can be defined accurately, which likewise sets the pattern for digital cellular systems

Optical Encoders and Decoders for OCDMA,which attempts to get to and from the mobile, subject to the propagation losses and multipath effects described earlier. Adding modulation widens the bandwidth of the signal. Ideally, a carrier has no bandwidth, but in practice, drift, noise and propagation produce observable bandwidth. Modulation p
