Turbo Coded Modulation For High-Throughput TDMA Systems
White Papers A high level modulation (8-PSK) was introduced in the evolution of GSM or EDGE. Using this modulation the maximum data throughput which can be achieved in the EGPRS protocol is 473.6kbps. For the next generation of mobile communications there is a...

Adaptive Modulation Techniques For Duplex OFDM Transmission
White Papers The design tradeoffs of turbo-coded burst-by-burst adaptive Orthogonal Frequency Division Multiplex (OFDM) wideband transceivers are analyzed. Upon invoking turbo coding and adjusting the modem mode switching regime near-error-free performance can...
