Assignment:
Consider a mobile communication system which has a framing and time-slot arrangement as shown below in Figure. There are a total of 4 time slots per frame; each user is assigned a single time slot per frame. Each time slot consists of 98 bits as shown in Figure. The signal-ing consists of QPSK modulation with a carrier frequency of 700 MHz. The symbol rate is 33.6 ksymbols/s, and the transmission bandwidth is 47 kHz. The system must perform normally at velocities up to 100 km/hr. Measurements performed on the physical channel conclude that the typical rms delay spread is in the order of 4 its
(a) Assuming that the training sequence yields an estimate of the channel impulse response during each slot time, will this design suffer the degradation effects of fast fading?
(b) Will this design suffer the degradation effects of frequency-selective fading?
Provide complete and step by step solution for the question and show calculations and use formulas.
