— We develop a semi-blind adaptive space-time shift keying (STSK) based multiple-input multiple-output system using a low-complexity iterative channel estimation and data detection scheme. We first employ the minimum number of STSK training blocks, which is related to the number of transmitter antennas, to obtain a rough least square channel estimate(More)
—The performance of Binary Phase Shift Keying (BPSK) in a Joint fading and Two-path Shadowing (JFTS) environment is analyzed. Closed form expression for the exact Average Bit Error Rate (ABER) of coherent BPSK scheme is presented using the Moment Generating Function (MGF) of the JFTS distribution. Finally the coherent BPSK ABER of a wireless communication(More)
—The ergodic and outage channel capacity of different optimal and suboptimal combinations of transmit power and modulation rate adaptation strategies over a Joint fading and Two-path Shadowing (JFTS) fading/shadowing channel is studied in this paper. Analytically tractable expressions for channel capacity are obtained assuming perfect channel side(More)
—The performance of Turbo coded Binary Phase Shift Keying (BPSK) over the Joint Fading and Two-path Shadowing (JFTS) environment is analyzed. Exact analytical expression for the Pairwise Error Probability (PEP) of Turbo codes over fully interleaved JFTS channels is presented using the probability distribution of the squared independent and identically(More)
An efficient and high-performance semi-blind scheme is proposed for Multiple-Input Multiple-Output (MIMO) systems by iteratively combining channel estimation with K-Best Sphere Decoding (SD). To avoid the exponentially increasing complexity of Maximum Likelihood Detection (MLD) while achieving a near optimal MLD performance, K-best SD is considered to(More)
