One-to-many optical information encryption transmission method based on temporal ghost imaging and code division multiple access

Photonics Research, 2019
A method is presented for one-to-many information encryption transmission by using temporal ghost imaging and code division multiple access. In the encryption transmission process, code division multiple access technologies combine multiple information ...

Coded multicarrier code division multiple access

Proceedings of 1995 IEEE International Symposium on Information Theory, 2002
This paper presents a multicarrier signaling technique for an asynchronous direct sequence (DS) code division multiple access (CDMA) system which employs linear convolutional codes to achieve performance gains in excess of path diversity gains realized in conventional single carrier RAKE DS CDMA systems.

Collaborative Reader Code Division Multiple Access in the Harmonic RFID System

IEEE Journal of Radio Frequency Identification, 2018
Reading reliability is a critical aspect in the ultrahigh-frequency radio frequency identification (RFID) system when a large amount of tags are in the reading zone with complex multi-path interferences. The read failure incidences can be caused not only

Code Division Multiple Access

2002
As already described in section 2.2.3, a direct sequence SS system can provide code division multiple access. This is performed by assigning each user a different code for the spectrum spreading process. Under ideal conditions and if these codes are chosen properly, there will be negligible interference between different users despite the fact that ...

Code-Division Multiple Access

2011
Multiple access is the ability of many users to communicate with each other while sharing a common transmission medium. Wireless multiple-access communications are facilitated if the transmitted signals are orthogonal or separable in some sense. Signals may be separated in time (time-division multiple access or TDMA), frequency (frequency-division ...
