• Code division multiple access (CDMA): Many channels occupies the same frequency band, at the same time. However, each channel occupies a different “code channel”. Like sinusoids at different frequencies are orthogonal (non-interfering), sets of code signals can also be made so that all code signals are orthogonal to each other.

2.0 Root Locus Design Consider all positive values of k. In the limit as k -> 0, the poles of the closed-loop system are a(s) = 0 or the poles of H(s). In the limit as k -> infinity, the poles of the closed-loop system are b(s) = 0 or the zeros of H(s). No matter what we pick k to be, the closed-loop system must always have n poles, where n is the

A digital communication system conveys discrete-time, discrete-valued information across a physical channel. Information sources might include audio, video, text, or data. They might be continuous-time (analog) signals (audio, images) and even 1-D or 2-D. Or, they may already be digital (discrete-time, discrete-valued). Our

It is considered along with antenna array gain to form a system with targeted equivalent isotropically radiated power (EIRP) and reasonable power efficiency.
