A limited amount of bandwidth is allocated for wireless services. A wireless system is required to accommodate as many users as possible by effectively sharing the limited bandwidth. Therefore, in the field of communications, the term multiple access could be defined as a means of allowing multiple users to simultaneously share the finite bandwidth with(More)
Burst transmission of digital data and voice has become commonplace, particularly in satellite communicat ion systems employing time-division multiple-access (TDMA) and packet demand-assignment mnltiple-access (DAMA) techniques. In TDMA systems particularly, phase estimation on each successive burst is a requirement, while bit timing and carrier frequency(More)
Performance of a wideband multipath-fading terrestrial digital coded communication system is treated. The analysis has applications to a cellular system employing direct sequence spread spectrum CDMA with M-ary orthogonal modulation on the many-to-one reverse (user-to-base station) link. For these links, pqwer control of each multiple access user by the(More)
