This enables high-resolution beamforming in both, the elevation and the azimuth domain, in order to achieve space-division multiple access gains through spatial separation of users, as well as to enhance the energy efficiency of wireless data transmission by concentrating the radiated energy towards intended users [1 3].
It is shown that the resulted directive, multiple access and multiplexing gains combined with scheduling, effectively increase both the spectrum spatial reuse and the capacity of the links and therefore, enhance the achievable system throughput.
Spectral Amplitude Coding – Optical Code Division Multiple Access systems are gaining popularity due to their property of very low multiple access interference.
In theory, that should be a boon for Qualcomm, whose code-division multiple access (CDMA) technology is gaining in popularity, and for the wireless equipment makers that license CDMA.
In this paper, we have introduced the notion of partial interference in wireless multiple access systems and illustrated the potential gain in system capacity when the effect of partial interference is taken into account.
CDMA has gained broad application in recent multiple access communication systems.
Qualcomm's CDMA (code division multiple access) technology — my leading technology enthusiasm since 1991 — has gained a nearly total worldwide triumph.
In [8], multiple code division multiple access (CDMA) channels were proposed, with a different processing gain for the SVC quality layers.
One such protocol that has gained great popularity is carrier sensing multiple access (CSMA).
The adoption of multiple antennas both at the transmitter and the receiver will explore additional spatial resources to provide substantial gain in system throughput with the spatial division multiple access (SDMA) technique.
