Abstract:
Pilot design schemes based on MIP requires a sufficient condition for the optimal pilot pattern generated from the CDS which depends on CIR. Since in most practical OFDM systems CIR does not exist thus optimal patterns are difficult to obtain in such conditions. To obtain a near optimal pilot pattern we propose three pilot design schemes .The first two schemes are based on stochastic search and other one is based on iterative group shrinkage. Simulation results shows that the proposed schemes converge much faster and out of which SSS and SPS schemes outperform the IGS schemes. Although both SSS and SPS result in similar Q values the former converges much faster than the latter. BER and MSE are also computed for these pilot designs.
