Sparse Recovery Algorithms for Pilot Assisted MIMO OFDM Channel Estimation
نویسندگان
چکیده
In this letter, the sparse recovery algorithm orthogonal matching pursuit (OMP) and subspace pursuit (SP) are applied for MIMO OFDM channel estimation. A new algorithm named SOMP is proposed, which combines the advantage of OMP and SP. Simulation results based on 3GPP spatial channel model (SCM) demonstrate that SOMP performs better than OMP and SP in terms of normalized mean square error (NMSE). key words: MIMO, OFDM, channel estimation
