Abstract :
Experimental results of 1.92 Mbps data transmission over a 20 MHz wideband DS-CDMA (W-CDMA) mobile radio link under frequency selective multipath fading are presented. The 1.92 Mbps data was transmitted using an orthogonal multicode transmission scheme. The combined use of antenna diversity reception, RAKE combining, and concatenated channel coding is applied to improve the transmission performance. The laboratory and field experimental results demonstrated the possibility of 2 Mbps data transmission under a real fading environment
