Abstract:
Adaptive windowing of insufficient cyclic prefix (CP) for joint minimization of intersymbol interference (ISI) and adjacent channel interference (ACI) is provided. The proposed subcarrier specific windowing scheme improves the signal-to-interference ratio (SIR) even when the cyclic prefix (CP) is insufficient. Average optimal window lengths depend only on the power density profiles (PDPs), and although instantaneous optimal window lengths depend on users' channel impulse responses (CIRs), fluctuation is little. Therefore, subcarrier specific windowing outperforms fixed windowing, even with outdated window lengths in the case of powerful interferers.

Claim (Index 9):
The media of  claim 6 , wherein estimating an optimal window duration for each of the plurality of subcarriers, wherein the optimal window duration is the duration that minimizes the aggregate adjacent channel interference (ACI) and intersymbol interference (ISI) at each of the plurality of subcarriers further comprises:\n estimating the aggregate ACI and ISI for a center subcarrier with no windowing; iteratively increasing a duration of the window of the center subcarrier and re-estimating the aggregate ACI and ISI, until a longest duration window that does not increase the aggregate ACI and ISI is identified as the optimal window duration of the center subcarrier; setting durations of windows for subcarriers adjacent to the center subcarrier to be equal to the optimal window duration of the center subcarrier; and iteratively increasing and decreasing the duration of the window for the adjacent subcarriers until a longest duration window that does not increase the aggregate ACI and ISI is identified as the optimal window duration of the adjacent subcarriers.
