In modern implementations of Cloud Radio Access Network (C-RAN), the\nfronthaul transport network will often be packet-based and it will have a\nmulti-hop architecture built with general-purpose switches using network\nfunction virtualization (NFV) and software-defined networking (SDN). This paper\nstudies the joint design of uplink radio and fronthaul transmission strategies\nfor a C-RAN with a packet-based fronthaul network. To make an efficient use of\nmultiple routes that carry fronthaul packets from remote radio heads (RRHs) to\ncloud, as an alternative to more conventional packet-based multiroute reception\nor coding, a multiple description coding (MDC) strategy is introduced that\noperates directly at the level of baseband signals. MDC ensures an improved\nquality of the signal received at the cloud in conditions of low network\ncongestion, i.e., when more fronthaul packets are received within a tolerated\ndeadline. The advantages of the proposed MDC approach as compared to the\ntraditional path diversity scheme are validated via extensive numerical\nresults.\n
