Numerical Simulations of a Cellular CDMA- Based Navigation System

The basic concept adopted in the cellular code division multiple access (CDMA)-based navigation system proposed in [1] very much resembles the Differential Global Positioning System (DGPS). The proposed system setup employs CDMA base transceiver stations (BTS) with an auxiliary mapping receiver used for estimating the BTS clock biases. The estimated BTS clock biases and the pseudorange measurements are employed in order to estimate the position and clock bias of the navigating receiver. We develop a code for the implementation of the proposed navigation system [1]. The code is implemented based on the experimental setup presented in [1] and the numerical results are compared with the experimental results reported in [1]. We discuss and analyze any inconsistency in the results. We also highlight few drawbacks of the proposed navigation system and present intuitive remedy for future consideration.
