Description
Transceiver design is a tradeoff between several parameters that impact on the transceiver
specifications. These parameters are also interrelated such that an increase in one parameter impacts on the possible
values of the second parameter and these determine the specifications achievable. This work presents the design of a
GSM transceiver system and presents that achieved results in comparison to the ETSI GSM specifications. The
parameters were all subjected to the same percentage variation and Matlab software was used to develop algorithms
for determining the variations and interrelationships between the parameters .One key criteria in transceiver design is
the Noise figure and the results show that the frontend comprising of the Duplexer, LNA, the Mixer has the greatest
impact on the transceiver design while the power amplifier noise figures have very minimal effect of the overall system
noise figure. It also shows the power amplifier as the unit that consumes the most power. From the results, several
power saving techniques such as sleep modes targeted at the Power amplifiers can be implemented without having any
significant effect on the transceiver speed, The results also show an inverse relationship between the overall system
gain and the dynamic range of the transceiver such that to achieve a higher dynamic range, the system gain would
have to be reduced. . This work enables an understanding of the relationships between the different parameters of the
GSM transceiver design
