Abstract: This talk will introduce a promising code-domain non-orthogonal multiple access scheme for 6G massive access, called sparse code multiple access (SCMA), whereby sparse codebooks are exploited to achieve higher spectral efficiency, typically by at least 50%. I will introduce its basic principles, new advances including power-imbalanced codebook design and OTFS-SCMA, as well as an SCMA hardware prototyping demo (see here and here) that can support concurrent picture and video transmissions.
Bio:Dr Zilong Liu is an Associate Professor and the 6G Lab Manager with the School of Computer Science and Electronic Engineering, University of Essex.
