This paper explores using a mobile platform for performing the calculations required for the building blocks of telecommunication systems. The building block analyzed in this paper is LDPC (low-density parity-check) channel decoding, performed on the LDPC design used in the DVB-T2 standard. Implementation details are given, and a performance analysis on a mobile CPU is performed. The implementation is compared against a very similar implementation running on a desktop computer CPU, as well as a GPU (graphics processing unit) implementation. The results give indications of the current state of typical mobile platforms of today.
