तो, रिसीव्ड सिग्नल (received signal) r(t) विभिन्न सिग्नल्स की L+1 कॉपीज़ (copies) का समेशन (summation) है जो चिप ड्यूरेशन (chip duration) t - LTc पर स्पेस्ड (spaced) है।
So, the received signal r of t is a summation of L plus 1 copies of different signals that have been spaced at chip duration t minus l Tc.
