Analysis on the use of EM algorithm for space time coding in fading channels
… method of partial detected frame in slow, flat fading channel, it is found that the use of partial frame to estimate the mean is able to improve the EM algorithm further. In the study, the use of a minimum 2 symbols results in a BER performance improvement of 2dB as compared to the use of the …

Adaptive MMSE multiuser receivers in MIMO OFDM wireless communication systems
… algorithm that is robust against slow and fast fading channel scenarios, in comparison to the conventional individual parameter estimation by E. Teletar in his famous paper of 1999. Implementing the Adaptive MMSE Receivers in MIMO OFDM systems which I refer to (AMUD MIMO OFDM), combines the …

EM-Based iterative channel estimation and sequence detection for space-time coded modulation
… transmitted over a wireless communication channel requires knowledge of the channel estimate. In this work, the application of expectationmaximization (EM) algorithm to estimation of unknown channel and detection of space-time coded modulation (STCM) signals is investigated. An STCM …

Design of single-carrier frequency domain equalization (SC-FDE) with transmit diversity for wireless and optical communications
… packets over the wireless communication channel. Broadband data transmission over wireless channels commonly faces the challenges of multipath fading channels, which are both time and frequency selective. There is then a need to design transmission techniques that can combat the adverse …

MIMO Communication Capacity: Antenna Coupling and Precoding for Incoherent Detection
… capacity of MIMO systems for compact arrays. For channels which do not vary in time, placing antennas closer together generally reduces the system capacity. However, recent work has demonstrated that for a MIMO system operating in a fast fading environment where the transmitter and receiver know …
