Synopsis

High data rates, low power consumption and low complexity are the most important parameters in the design of the next generation mobile terminals. In this thesis we are introducing a new paradigm in the design of a direct sequence (DS) spread spectrum (SS) receiver by combining analog and digital signal processing. The main difference with respect to the conventional all-digital SS receiver design approach is that the proposed mixed analog/digital processing results in a symbol rate sampling rather than the high rate sub-chip sampling. The analog signal despreading is a key part of the proposed receiver solution. The potential advantages of analog despreading are reduced power consumption and low receiver complexity. Also, the proposed receiver solution allows very high chip rates (very high signal bandwidth). The solution is based on a five port device, a passive RF square law type of device. It is used to perform two important tasks at the same time, namely, the direct conversion and the analog despreading.
