Abstract
An efficient Schnorr-Euchner enumeration (SEE) to perform sphere decoding (SD) in digital communication applications is proposed. In this paper, we devise the elaboration of the enumeration step and counting the visited valid points in order to improve SEE procedure. Compared to the conventional SEE based on a simple zig-zag manner, the proposed SEE shows reduced complexity without any performance degradation.
