Non Coherent Detection in the Context of Coded Communication

In today’s world of Spread Spectrum based coded mobile communication, security and anti jamming features are added in the physical layer which enhance the performance of mobile devices as compared to existing GSM based uncoded communication. The authors are encouraged to utilize this 3G mobile technology to their PCN ( personnel communication networking ) wireless system. A DSSS based wireless devices are implemented in their PCN system. A microcontroller based network layer is interfaced with the DSSS based physical layer to form the PCN and an additional level of security is added in the CODEC part of the network layer. It therefore, requires a second level of detection and decoding where non coherent mode of detection is utilized to ease the system operation.
