Orthogonal Frequency Division Multiplexing (OFDM) is a very attractive technique for high data rate transmission with good bandwidth efficiency. OFDM system utilize the cyclic prefix (CP) to mitigate the effect of inter symbol interference (ISI) produced by the multipath effect of wireless channel. The CP insertion only mitigates the effect of inter block(More)
This paper analyzes the performance of a selective Decode-and-Forward (DF) protocol based cooperative space-time block coded spatial modulation (STBC-SM) MIMO system. Further, the analysis is presented for a Kronecker MIMO channel model considering spatial correlated channel conditions. The results are also derived for the diversity order of the system(More)
—An off-axis pole focusing method for robust direction of arrival (DOA) estimation is presented in this paper. The roots (poles) of the root-MUSIC polynomial are generally evaluated over the unit circle in the z-domain. The DOAs can be computed from these poles using a simple geometric relation. Rather than computing the root-MUSIC polynomial over the unit(More)
Symmetric symbol repeat (SSR) intercarrier interference (ICI) self cancellation scheme has proved to be a simple and convenient technique to reduce ICI caused by frequency offsets. It utilizes data allocation and combining of (1,-1) on two symmetrically placed subcarriers to mitigate the effect of ICI. However, the data allocation factors (1,-1) are not an(More)
