Title
Wireless SPIHT-encoded image transmission employing hierarchical modulation: A DSP implementation
Abstract
In this paper, the performance of wireless transmission of SPIHT-encoded images employing Hierarchical Quadrature Amplitude Modulation (HQAM) is investigated with an experimental test-bed. Two Texas Instruments (TI) Digital Starter Kits (DSK), each one equipped with the floating point DSP chip TMS320C6713, are employed for the system testing, one for the transmitter and one for the receiver. The digital signal processing that formats the information data in preparation for transmission as well as the digital signal processing that recovers the information data at the receiver site are described in detail. Various results measuring bit error rates and peak signal-to-noise ratios are presented to demonstrate the performance of the experimental setup under various channel conditions, for different values of the modulation parameters.
