• They were allocated a total bandwidth of about 2 MHz. Frequency modulation (FM) was used. For multiple user access, the system operated frequency division multiple access (FDMA), in which each channel was allocated a non-overlapping frequency band within the 2 MHz.

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

Orthogonal Frequency Division Multiplexing (OFDM) Modulation - a mapping of the information on changes in the carrier phase, frequency or amplitude or combination. Multiplexing - method of sharing a bandwidth with other independent data channels. OFDM is a combination of modulation and multiplexing. Multiplexing generally refers to

modulation schemes almost exclusively. Although LTE uses OFDM rather than single carrier modulation, it’s instructive to briefly discuss how single carrier systems deal with multipath-induced channel distortion. This will form a point of reference from which OFDM systems can be compared and contrasted.

For example, the 11ac PHY is based on the well known OFDM (Orthogonal Frequency Division Multiplexing) PHY used for 11a and 11n and will maintain the same modulation, interleaving and coding architecture of 11n. However, some modifications and new 11ac features/parameters are necessary to meet 11ac™s goals.
