This letter discusses how to enhance the capacity of uplink DS-CDMA networks that support multihop transmission. For this purpose, we derived simple theoretic conditions by which one can choose between singlehop- and multihop transmission. Numerical results show that we can significantly increase the radio network capacity by adopting only a few number of multihop transmissions.
