High-speed indoor wireless communications at 60 GHz with coded OFDM

A high-speed indoor wireless communication system using coded orthogonal fr equency-division multiplexing (OFDM) and working at 60 GHz is proposed and analyzed, An actual propagation environment consisting of a medium-sized re search laboratory, characterized by means of a ray-tracing technique, is co nsidered for the analysis. In this context the paper investigates and discu sses the effects of frequency diversity, antenna sectorization, OFDM cluste ring, and different block coding strategies. Moreover, to characterize the communication between stationary indoor terminals at millimeter waves, a ne w definition of coverage is introduced. In order to evaluate the performanc e of the coded system in the actual environment, a suitable semianalytical algorithm is defined and applied. In the results the feasibility of a coded OFDM system for 155 Mbit/s Packet transmission is checked. It is shown tha t all the line-of-sight (LOS) positions and 70% of the no LOS points can be covered in the scenario considered with a transmitted pow er of 10 dBm.
