a.Given the baud rates of 8 kBd and 64 kBd, calculate the bit rate for the modulation of BFSK, BASK, BPSK, QPSK, 16-PSK, 4-QAM, 16-QAM, and 64-QAM
b. Given a data stream of a bit rate 56 kbps or 256 kbps, what are the chip rate and process gain if the 11-bit or 13-bit Barker code is used as the PN code to spread the data stream?
Â
c. What are the major differences between synchronous CDMA and asynchronous CDMA?
d. Compare the PN codes and the orthogonal codes used in CDMA. Why can we support more users with PN codes than with orthogonal codes?
