NOMA

 Answer:-  In an orthogonal multiple access (OMA) system, like TDMA and FDMA, orthogonal resource allocation is employed among users to avoid intra-cell (inter-user) interference. The number of supported users is constrained by the available orthogonal resources. In OMA, each user is assigned a fixed frequency band. However, in NOMA, all frequency bands can be utilized by each user, as illustrated in the figure above. NOMA allows and mitigate intra-cell interference in resource allocation of users. So, according to the Shannon Capacity Equation, C = B log 2 (1+S/N) The data rate is directly proportional to the bandwidth.  In NOMA, we get a large frequency band. So, we can improve the data rate with the help of NOMA.

 Answer- NOMA stands for non-orthogonal multiple access. It enables multiple users to share a single resource, thereby enhancing both user experience and the overall system throughput.

 You can use randi function to generate a signal.  For example:- We have to generate a column vector of random data. Syntax:-  x = randi ([0,1],number of bits, 1)  where the first input is a range of bits The second input is the number of rows The Third input is the number of columns
