CHAPTER TENMultiple-Access Techniques10.1 INTRODUCTIONThree commonly used techniques for accommodating multiple users in wirelesscommunications are frequency division multiple access (FDMA), time divisionmultiple access (TDMA), and code divisio[r]

Keeping the average transmission power constant, we show that the TOA accuracy of each user does not depend on its transmissionprobability, while being a nondecreasing function of the transmission probability of any other user. Therefore, a generalized,noncontinuous CDMA system with a probability co[r]
