Abstract :
A new bandwidth efficient multiple access (BEMA) scheme for mobile radio is introduced. It offers a higher spectral efficiency than dynamic time division multiple access. This idea must be understood from the viewpoint that BEMA results from optimizing over a class of correlated waveform multiple access (CWMA) strategies that includes TDMA as a special case. At the heart of this new BEMA technique are signal processing algorithms that realize the functions of multiuser equalization and signal design, and which are developed by taking a new and combined approach to those two problems
