Abstract :
In this paper, we propose a zero-padded (ZP) packet transmission scheme for forward link packet data channel (F-PDCH) of cdma2000 1x EV-DV. The system utilizes the quasi complementary Turbo codes (QCTC) to adjust its packet format to be modulated in ZP single-carrier frequency domain equalizer (FDE) symbol units while the subpacket structure of forward link packet data channel is preserved. Thus, by allowing a slight modification to the standard, backward compatibility is maintained to the existing 1x EV-DV system. We report that the link-level performance of our system is significantly better than previous equalizer-based systems in frequency selective fading channels.
