Abstract

A noncoherent PN code tracking loop in a fully digital modem is investigated for bandlimited direct-sequence spread-spectrum communications. Its main features are low hardware complexity and good tracking performance. Analytical expressions of the error characteristics and steady-state timing jitter are derived and confirmed by means of computer simulation. The numerical results show that it achieves good steady-state performance. In addition, the proposed technique provides good resistance to multiple-access interference while operating in a code-division multiple-access environment.
