Assignment:
A mobile wireless system is configured to support a data rate of 200 kbits/s using QPSK modulation and a carrier frequency of 1900 MHz. Tt is intended for use in a vehicle that typically travels at a speed of 96 km/hr.
(a) What change in phase angle value, AO per symbol, can be expected?
(b) What is the value of AO per symbol, if the data rate is decreased to 100 kbits/s?
(c) Repeat part (b) for a speed of 48 km/hr.
(d) Draw some general conclusions.
Provide complete and step by step solution for the question and show calculations and use formulas.
