Description
Book SynopsisThe book is based on the observation that
communication is the central operation of discovery in all the sciences. In its active mode we use it to interrogate the physical world, sending appropriate signals and receiving nature''s reply. In the passive mode we receive nature''s signals directly. Since we never know
a prioriwhat particular return signal will be forthcoming, we must necessarily adopt a probabilistic model of communication. This has developed over the approximately seventy years since it''s beginning, into a Statistical Communication Theory (or SCT). Here it is the
set or
ensemble of possible results which is meaningful. From this ensemble we attempt to construct in the appropriate model format, based on our understanding of the observed physical data and on the associated statistical mechanism, analytically represented by suitable probability measures.
Since its inception in the late ''30''s of the last century, and in particular subsequen
