Let us say that it is a discrete channel that is between the transmitter and receiver. So, in a SISO case if it was just a flat fading channel you would represent it by some coefficient z 1. Now if it was a time it is a basically it is a time dispersive, then it becomes z 1 and then there is a z 2 with the different delay, there is a maybe there are some number of taps that are present in the system.
अगर ट्रांसमीटर और रिसीवर के बीच एक डिस्क्रीट चैनल है तो, SISO केस में, अगर सिर्फ एक फ्लैट फेडिंग चैनल है तो आप इसे गुणांक Z1 द्वारा दर्शाएंगे। अब टाइम डिस्पर्सिव चैनल में {Z1, Z2,. . . ZL } होगा, क्यूंकि वहां डिले के साथ कुछ और टेप्स भी सिस्टम में मौजूद होंगे।
