2D Markovian SS codes flatten time-frequency distribution of signals in asynchronous Gabor division CDMA systems
We propose a Gabor division (GD)-CDMA system which permits time and frequency offsets. Negatively correlated time- and frequency-domain spreading codes have shown to reduce the va...

Precoded Block-Spread CDMA with Maximum User Support and Frequency-Domain Equalization
Abstract—Block-spread code-division multiple access (BSCDMA) is a bandwidth efficient method by which multiple users can utilize a transmission medium simultaneously. One specia...
