Abstract: From the frequency usage efficiency points of view, the novel diffCDMA with continuous chip shaping is proposed in this paper to achieve such high reliability as shown in free space propagation. Continuous chip shaping is facilitated by substituting smoothing function over adjacent chip fringes, in which the function touches current and next chips with 0th order contact and varies with the steepest gradient just at the center The diffCDMA is verified through simulations over such urban multi-ray Rayleigh fading environment as poor and narrow 4MHz bandwidth radio channel for 1.6Mbps transmission via 4Mcps to be error free by employing both continuous chip shaping in direct spectrum scrambling and BCH(63, 51) double error correction code.
