A Feasibility Study On C-RAN

Abstract

Now a days the number of users of mobile phone are increasing exponentially, so it will
cause jamming in the network and require large bandwidth So among promising technology
candidates to overcome this problem, cloud radio access network (C-RAN) used. C-RAN,
having one baseband unit (BBU) communicates with users through distributed Remote Radio
Heads (RRHs) .RRH are connected to the BBU via high capability, low latency fronthaul
links and performs soft relaying. The architecture of C-RAN imposes a shortage of fronthaul
bandwidth because raw I/Q samples are exchanged between the RRHs and the BBU. In BBU
different algorithms are used to improve the capacity, joint decompression and decoding
(JDD) and wyner ziv coding.
