Abstract

The era of wireless has just begun, which is a good sign for people to get communication faster and in a reliable manner at any place. This demanding situation for mobile communication is fulfilled if one provides a good communication method at low cost. Bandwidth and power are the main concerns for this type of communication. The QPSK method offers the best trade-off between these two. For a robust receiver structure, one has to switch from coherent detection to differential detection. The bit error rate gap between the coherent and the differential can be reduced by the application of a technique which uses adaptive algorithms
