In this paper, a low-complexity spread spectrum system with M-ary cyclic-shift keying (MCSK) symbol spreading is proposed. In addition, by using the minimum-shift-keying (MSK) as the chip-level modulation, we obtain a high-rate QPSK-MCSK transceiver scheme which not only provides a constant-envelop
