Millimetre wave wideband communication performance for various corridors

A comparison of wideband communication characteristics for five different geometrical configurations of corridors at 57.5 GHz is investigated. Shooting and bouncing ray/images techniques are applied to compute the impulse responses for: (i) the straight shape corridor with rectangular cross section, (ii) the straight shape corridor with arched cross section, (iii) the curved shape corridor with rectangular cross section, (iv) the curved shape corridor with arched cross section and (v) the L-shape corridor. By using the impulse responses of these multipath channels, the outage probabilities for high-speed BPSK (binary phase shift keying) systems with phase and timing recovery circuits are calculated. Numerical results show that the outage probability for the L-shape corridor is the largest among all the five configurations being studied. Also, the outage probabilities for the arched cross section corridors are smaller than those for the rectangular cross section corridors regardless of the shapes. In addition, the effect of space antenna diversity techniques on mitigating the multipath fading is also investigated
