A review of codebook design methods for sparse code multiple access

<span lang="EN-GB">The progressions in telecommunication beyond the 5<sup>th</sup> generation have created a need to improve research drifts. The current 5G study has an important focus on non-orthogonal multiple access (NOMA) technology. sparse code (SCMA) is promising technique within NOMA, enhancing multi-user handling capability of next-generation communication. In SCMA sphere, codebook designing and optimisation are essential matters. This conversed with different design practises existing literature, analysing them for numerous parameters, including bit error rate (BER), technique, channel settings. From analysis, paper presents efficiency approaches. article also discusses prospects challenges practical implementation various domains.</span>
