Abstract—In a mobile ad-hoc network scenario, where communication nodes are mounted on moving platforms (like jeeps, trucks, tanks, etc.), use of V-BLAST requires that the number...
— We analyze the user capacity of downlink CDMA systems with quasi-orthogonal sequences(QOSs) considering various system parameters, such as user activity, spreading factor, the ...
—The IEEE 802.15.4 standard specifies an M-ary spread spectrum system with public and fixed spreading sequences. We propose instead to use secret and dynamic, random spreading ...

Abstract-- We consider code division multiple access communication over a binary input additive white Gaussian noise channel using random spreading. For a general class of symmetri...
