Adaptation of Modulation, Coding, and Power for High-Rate Direct-Sequence Spread Spectrum

Communication devices that employ adaptive transmission protocols can exploit good channel conditions to increase throughput and compensate for poor channels to enhance survivability. We examine the performance of a protocol for the combined adaptation of the modulation, error-control-code, and tran...

Description
Summary:Communication devices that employ adaptive transmission protocols can exploit good channel conditions to increase throughput and compensate for poor channels to enhance survivability. We examine the performance of a protocol for the combined adaptation of the modulation, error-control-code, and transmitter power in high-rate direct-sequence spread-spectrum systems. The protocol requires only simple statistics that are obtained easily from the demodulator and decoder, and only a few bits of feedback are required in each acknowledgment packet.
