Abstract
This paper presents a novel memory optimization technique to exploit the analogy between correlation coefficients in MMSE-based channel estimators across multiple standards. The need for coefficient storage for robust MMSE channel estimators is expensive in terms of on-chip memory. Besides, the memory requirements grow linearly by integrating more standards onto one platform. Thus, it becomes inevitable to address the increased on-chip memory problem for such estimators. In this paper, we have shown that by exploiting the inherent similarities between LTE and DVB-H design parameters, a three-fold memory optimization may be achieved with minimal performance loss.
