Closed loop space-time block code

IEEE 54th Vehicular Technology Conference. VTC Fall 2001. Proceedings (Cat. No.01CH37211), 2001
In 3GPP FDD specifications, space time transmit diversity (STTD) employs space-time block code (STBC) to maintain orthogonality between the two antennas in order to avoid self-interference in fading channels. However, the STTD technique is just open loop

Multicarrier transmission peak-to-average power reduction using simple block code

, 1998
A simple added-bit block code suitable for transmission in multicarrier systems is presented. It is applied across the carriers and offers a reduction in peak-to-average power ratio, without significantly reducing overall efficiency or increasing ...

Lower bounds on the minimum hamming distance achievable with runlengh constrained or DC free block codes and the synthesis of a (16,8) D min = 4 DC free block code

, 1984
Error correction coding gain can be obtained with dc free magnetic recording codes having a minimum Hamming distance d_{\min}\geq 4 . In this information theoretic paper we establish lower bounds on the minimum Hamming distance achievable with (2n,k) (ie
