Abstract :
The concept of channel assignment in adaptive TDD (ATDD) fixed wireless networks is addressed in this paper. A novel rotated-interleaved channel assignment (RICA) scheme is proposed that improves throughput, compared to existing schemes, by up to 9% inducing no further costs. Furthermore, the spectral efficiency between FDD and ATDD modes of operation is investigated considering the same network characteristics and RICA. It appears that according to the traffic asymmetry variations as expressed in the moving TDD boundary, the throughput performance of ATDD is from 2% to 14% less than that of FDD.
