In this paper, we study a wireless infrastructure mesh network where nodes are equipped multiple frequency-hopping radio interfaces, each with an array of antennas and utilizing the space-time block coding (STBC) technique for transmissions. With STBC technique on the radio, both temporal and spatial diversities can be employed on each transmission and the channel-attenuated performance can then be improved. Then, to reduce the cochannel interferences in the multiradio mesh network , we present an interference-aware channel assignment algorithm to evaluate the amount of cochannel interferences using an SER (symbol eror rate)-based cost function and assign the most appropriate hopping pattern for each radio. Using the STBC physical technique along with the MAC-layer channel management, the mesh network thus acquires the immunity against the channel attenuation and the cochannel interferences.
