Assignment:
Q1. Consider a CDMA direct-sequence cellular telephone system, where each user requires an Eb/I0 of 6 dB for acceptable voice quality. The chip rate is 3.68 Mchips/s, and the data rate is 14.4 kbits/s. Assume that the factors -y, Gv, and H0. are 1.5, 2.5, and 1.5, respectively, and that transmission ceases during speech pauses. How many users per cell can be supported?
Q2. If a powerful error-correcting code is used to lower the required Eb/4 by 1 dB, how many users per cell can be supported?
Provide complete and step by step solution for the question and show calculations and use formulas.
