In this paper we present the design, implementation and realization of a receiver for a wireless nano-cellular ATM network using a small Field Programmable Gate Array. The network is designed for an office environment. The method used for transmitting data, at the rate of 1Mbps, is Differential Phase Shift Keying (DPSK) on a 3 MHz carrier using near-field RF. It uses differential coherent detection to demodulate the received signal. A matched filter combined with a notch filter reduces the bit error rate. A MAC protocol for this network that is suitable for multimedia traffic is implemented in a micro-controller. The system has been demonstrated in a setup where uncompressed video frames (320x200x6) were transmitted at a rate of 4 frames per second.
