Abstract EN
By combining adaptive modulation and automatic repeat request, a cross-layer design (CLD) scheme for MIMO system with antenna selection (AS) and imperfect feedback is presented, and the corresponding performance is studied.
Subject to a target packet loss rate and fixed power constraint, the variable switching thresholds of fading gain are derived.
According to these results, and using mathematical manipulation, the average spectrum efficiency (SE) and packet error rate (PER) of the system are further derived.
As a result, closed-form expressions of the average SE and PER are obtained, respectively.
These expressions include the expressions under perfect channel state information as special cases and provide good performance evaluation for the system.
Numerical results show that the proposed CLD scheme with antenna selection has higher SE than the existing CLD scheme with space-time block coding, and the CLD scheme with variable switching thresholds outperforms that with conventional-fixed switching thresholds.
