4) a. A TDMA System operates at 125Mbps with a 2.5ms frame time asume that all slots are equal length and that a guard time of 2 us is required between slots i. Compute the efficiency of the communication resource for the case of 1,2,5,10,20,50 and 100 slots per frame. (5 Marks) ii. Repeat part I assuming that a 100 bit preamble is required at the start of each slot.Compute the efficiency of the communication resource in terms of the desired information transmission (5 Marks) iii. Plot the results of part i and partii (2 Marks) MEC_AMO_TEM_035_01 Page 3 of 8 Digital Communication (ELEC 20004) - Spring - 2020 - CW (Assignment) All - QP b. Consider convolutional encoder with constraint length=4. The connection vectors are given by 91 = [1011), 92 = [1 101) and 93 = [1010). i. The encoder Diagram; (3 Marks) ii. State Transition Table; and (5 Marks) iii. State diagram. (5 Marks) 4) a.
