Space-Time FSK: An Implicit Pilot Symbol Assisted Modulation Scheme

We develop in this paper an Alamouti-type space- time (ST) block code that employs orthogonal M-ary FSK (MFSK) modulation. It is demonstrated that every transmitted symbol in the proposed ST-MFSK scheme can be treated as an implicit pilot symbol, and consequently the receiver can attain close to ideal coherent bit-error performance even in the absence of an… (More)
