30. On Galois-Division Multiple Access Systems: Figures of Merit and Performance Evaluation
A new approach to multiple-access based on finite field transforms is investigated.
These schemes, termed Galois-Division Multiple Access (GDMA), offer compact bandwidth requirements.
A new digital transform, the Finite Field Hartley Transform (FFHT) requires dealing with
fields of characteristic p (p different to 2). A binary-to-p-ary mapping based on the
opportunistic secondary channel is introduced. This allows the use of GDMA in conjunction with
available digital systems. The performance of GDMA is also evaluated.
