Abstract

In this paper, we have proposed and designed a code quadratic frequency shift keying technique based frequency hopping (CQFSK/FH) spread spectrum signaling for multichannels of wireless personal communication. The dependence of BER and bandwidth on hope size of the technique is shown. It is seen that the bandwidth of the proposed signaling scheme with four channels is five times less than that of existing code M-ary frequency shift keying based frequency hopping spread spectrum (CMFSK/FH) system of same number channels with almost same BER of 7x10^-^4 at optimum hope size of 0.5MHz.
