A novel type of noncoherent homodyne receiver is presented. It is designed for low-cost mobile communication applications in the upper UHF area. The receiver operates on digital angle-modulated signals at high data rates in GMSK and in most other two- and four-state modulation schemes of the proposed European DECT-standard, as well as one more frequency-efficient linear modulation techniques. The design of the RF and mixing circuits, as well as the baseband filtering and the vector-operation-based demodulation circuit are presented. Some computer simulations of the operating performance of this receiver system are described.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
