    Sammanfattning : Bandwidth efficiency is a key objective in the design of a digital communication system. Traditionally it is accomplished by increasing the constellation size of the signaling system. In this thesis alternative techniques are studied. Because the communication channel is continuous, so must the actual time signals be. LÄS MER
