Construction of block orthogonal golay sequences and application to channel estimation of mimo-ofdm systems
In this paper, we construct a family of block orthogonal Golay sequences that have low peak-to-mean envelope power ratio (PMEPR) as well as blockwise orthogonal properties. We then...

Two novel compressed-sensing algorithms for NBI detection in OFDM systems
We propose two novel algorithms based on compressed-sensing theory to estimate and cancel narrow band interference (NBI) in orthogonal frequency division multiplexing (OFDM) syste...
