The author in [4] proposed a high spectrum efficient multiple access code.
Assisted by the multiple access code, the above scheme can not only achieve synchronization acquisition, but also activate a mass of tag receivers.
We present, for the first time, several aspects of incoherent optical code-division multiple access (OCDMA) codes, focusing on the flexible variable cross-correlation code allocation and its potential for future optical networks.
In this paper, we present, several aspects of unipolar optical code-division multiple access (OCDMA) codes, focusing on the flexible in-phase cross-correlation code algorithm and its potential for future optical networks.
At this stage, readers also exchange information for negotiating their UWB codes for backscattering communication operation that will be used to perform multiple access under code division multiple access (CDMA) technique.
N different users can be allocated N different unique SS codes with the length N. In the mobile communication network applying code division multiple access (CDMA), the users' SS codes are assigned by the base station.
This third approach used a form of spread spectrum multiple access known as code-division multiple access (CDMA)—a technique that, like the original TIA approach, combined digital voice compression with digital modulation.
The set of deterministic MAC methods includes master-slave schemes, token passing schemes, TDMA, frequency division multiple access (FDMA), and code division multiple access (CDMA).
In the code domain, the sparse code multiple access (SCMA) is presented in [45].
Different storage facilities have different amenities: climate-controlled units, security cameras, gates with access codes, multiple stories.
