与理论和实践上都已被充分理解的单会话网络编码相比，多会话无线网络编码的一般性问题仍然是一个挑战。在本文中，我们扩展我们的单会话网络扩频编码方案（NSC）更一般的多会话NSC（MS-NSC）计划。与直接的NC相比，MSNSC使用线性独立的完全互补（CC）序列作为编码向量，以促进在遭受衰落、干扰和噪声的无线信道上的通信。与经典NC相反，MS-NSC不需要中间编码节点（由于信道的物理特性）。AWGN和平坦衰落信道下获得的结果表明，在多会话的情况下，只有最小的性能损失相比，在单会话的两个建议的MS-NSC操作模式。
Contrary to single-session network coding which is well understood in both theory and practice, the general problem of multi-session wireless network coding is still a challenge. In this paper, we extend our single-session Network spread coding scheme (NSC) to the more general multi-session NSC (MS-NSC) scheme. In contrast to straightforward NC, MSNSC uses the linearly independent complete complementary (CC) sequences as encoding vectors that facilitate communication over wireless channel suffering from fading, interference and noise. As opposed to classical NC, MS-NSC requires no intermediate encoding nodes (due to the physical characteristic of the channel). Results obtained under AWGN and flat fading channels demonstrate only minimal performance loss in the multi-session scenario compared to that in the single-session for the two proposed MS-NSC operating modes.
