Project Title: Continuous Phase Modulation

Introduction:

Continuous Phase Modulation (CPM) is a power and bandwidth efficient modulation scheme

mainly used for its attractive spectral efficiency. There are many forms of CPM developed

for mobile and fixed communications: partial response CPM, trellis‐coded CPM, multi modulation index (h) CPM, multi‐T CPM, nonlinear CPM, multi‐amplitude CPM and quadrature‐multiplexed CPM.

Objective:

The objective of this project is to study the baseband signal models of various CPM schemes and investigate detection techniques that can be employed. Then apply MATLAB and Simulink to model a selected CPM modulation scheme (e.g., MSK or CPFSK)

in an AWGN channel to compute error probability. Statement of the problem, tasks and deliverables:

• The major problem with current mobile and other personal communication systems is the limited bandwidth available for high‐data rate services. This calls for spectrally‐efficient modulation schemes to be used in data transmission.

• Literature survey on CPM schemes with special emphasis on full‐response systems such as MSK and CPFSK.

• Use MATLAB and Simulink to implement in baseband one MSK or CPFSK based modulation scheme for data transmission over an AWGN channel. Use appropriate performance measures for the type of modulation you have chosen.

• Write a report of not more than 4,000 words. Use UWS Harvard system or the IEEE style for referencing.
