We consider the problem of information flow over Gaussian relay networks. Similar to the recent work by Avestimehr et al. [1], we propose network codes that achieve up to a constant gap from the capacity of such networks. However, our proposed codes are also computationally tractable. Our main technique is to use the codes of Avestimehr et al. as inner codes in a concatenated coding scheme.
