Comparing the Performance of MSK and GMSK on a Noisy Link

Discussion of MSK and GMSK

The Task.

You are asked to examine the performance of Minimum Shift Keying (MSK) and Gaussian Minimum Shift Keying (GMSK).

You should use SIMULINK to produce simulations which will compare the performance of MSK and GMSK on a noisy link using the individual data provided below.

Individual data

You have been given some individual data in the table below. You should use SIMULINK to simulate the data stream being encoded using MSK and GMSK and compare the two under the conditions you have been given. In addition to your own data from the table, you should investigate the effect of a range of values for BT and SNR. At a minimum, your results should include constellation diagrams and eye diagrams. Other measurements are available.

(v) the use of mobile phones or any other communication device during an assessment or examination;

(vi) the submission of false claims of previously gained qualifications, research or   experience in order to gain credit for prior learning;

(vii) the falsification of research data, the presentation of another’s data as one’s own, and any other forms of misrepresentation in order to gain advantage;

(viii) the submission of work for assessment that has already been submitted as all or part of the assessment for another module without the prior knowledge and consent of the Module Leader for the subsequent assessments;

(ix) the submission of material purchased or commissioned from a third party, such as an essay-writing service, as one’s own.

Plagiarism is defined as the representation of the work, artefacts or designs, written or otherwise, of any other person, from any source whatsoever, as the student's own.  Examples of plagiarism may be as follows:

i) the verbatim copying of another's work without clear identification and acknowledgement including the downloading of materials from the Internet without proper referencing of materials;

iii) the unidentified and unacknowledged quotation of phrases from another's work;

iv) the deliberate and detailed presentation of another's concept as one's own

Collusion includes:

(i) the conscious collaboration, without official approval, between two or more students in the preparation and production of work which is ultimately submitted by each in an identical or substantially similar form and/or is represented by each to be the product of his or her individual efforts;

(ii) collusion also occurs where there is unauthorised co-operation between a student and another person in the preparation and production of work which is presented as the student's own.
