Abstract
Detecting the presence of a valid signal is an important task of a telecommunication receiver. When the receiver is unable to detect the presence ofa valid signal, due to noise and fading, it is referred to as an erasure. Thiswork deals with the probability of erasure computation for orthogonalfrequency division multiplexed (OFDM) signals used by multiple inputmultiple output (MIMO) systems. The theoretical results are validated bycomputer simulations. OFDM is widely used in present day wireless communication systems due to its ability to mitigate intersymbol interference(ISI) caused by frequency selective fading channels. MIMO systems offerthe advantage of spatial multiplexing, resulting in increased bit-rate, whichis the main requirement of the recent wireless standards like 5G and beyond.
