Multi-Gbps wireless systems over 60-GHz SiGe radio link with BW-efficient noncoherent detections

This paper describes a demonstration of multi-Gbps wireless systems using 60-GHz SiGe radio chipsets with noncoherent detection techniques. The modulation and demodulation are performed with BW-efficient frequency-shift keying schemes, such as MSK, by partitioning the function into the radio chip and baseband FPGA. With integrated mixer/sign modulator and appropriate precoder, an IQ-based radio interface is used in TX, while the noncoherent detections are achieved by using FM discriminator and CDR (Clock Data Recovery) in RX, As a result, multi-Gbps data rate systems can be built without using high sampling rate ADC/DAC, and the efficiency better than ASK or FSK modulation schemes is achieved. © 2008 IEEE.
