In this paper, the effect of frequency offset on the performance of downlink OFCDM systems with variable spreading factors is investigated. The bit error rate of downlink VSF-OFCDM is analyzed taking into account the effect of carrier frequency offset when subcarrier grouping is used. An analytic expression of the SINR for downlink OFCDM with frequency offset using BPSK modulation is derived for the...
Inexpensive navigation-grade receivers are insufficiently accurate for the task of building a Global Navigation Satellite System [GNSS]-based parking meter for urban multipath conditions. Survey-grade instruments that demonstrate cm accuracy are inappropriate, and are two orders of magnitude too expensive, for this mass application. We identify three ways in which a digital signal processor added...
