64.8 GHz wireless personal area network characterisation using single-carrier frequency domain equalisation for indoor channels

Single-carrier transmission with frequency domain equalisation (SC-FDE) is one of the candidates for the next generation indoor wireless personal area networks operating at millimetre waves in the frequency band around 60 GHz. In this study, a 64.8 GHz SC-FDE wireless mobile radio system is presented and its back-to-back performance verified. The transceiver employs fractionally spaced minimum mean-square-error frequency domain equalisation, that is, compliant with the IEEE 802.15.3c millimetre-wave standard. Results of experiments, undertaken at 64.8 GHz in a number of indoor environments, to characterise the effectiveness of the SC-FDE technique to mitigate the effects of multipath propagation are presented for line-of-sight and non-line-of-sight scenarios. Bit-error-rate performance for 16-quadrature amplitude modulation 100 Mb/s transmission is given as a function of signal-to-noise ratio for a combination of omnidirectional and directional antennas at both terminals and compared with that obtained in additive white Gaussian noise channel.
