On self-dual and LCD double circulant and double negacirculant codes over $F_{q} + u F_{q}$

Minjia Shi, Hongwei Zhu, Liqin Qian +2

Double circulant codes of length $2 n$ over the semilocal ring $R = F_{q} + u F_{q}, u^{2} = u,$ are studied when $q$ is an odd prime power, and $- 1$ is a square in $\mat…

Linear codes with few weights over $F_{2} + u F_{2}$

Minjia Shi, Liqin Qian, Patrick Sole

In this paper, we construct an infinite family of five-weight codes from trace codes over the ring $R = F_{2} + u F_{2}$ , where $u^{2} = 0.$ The trace codes have the algebraic…
