....indicate that the algorithm performs particularly well in situations with very few data samples. 1. INTRODUCTION Space time block codes (STBCs) take advantage of the presence of multiple antennas to introduce redundancy in the transmitted data and achieve spatial diversity. As shown in [1, 2, 3, 4, 5, 6, 7], this redundancy can also be exploited for (semi )blind source separation or equalization. In [7] a subspace based equalization algorithm was presented and shown to be applicable to a wide class of STBCs. The algorithm can be used to directly estimate the underlying transmitted sequence, the ....

....expressions of steady state channel MMSE at each data symbol position, which is useful to evaluate the performance of coded transmissions. Optimal training has been previously considered for block fading channels from a channel estimation perspective under both TDM and superimposed trainings [9, 5, 2] and from an information theoretic angle in [10, 1] For time varying channels, Cavers first analyzed the pilot symbol assisted modulation (PSAM) 3] that includes the periodic TDM training with cluster size one the RPP 1 placement. While the optimality of RPP 1 has never been shown for either ....

Optimal training has been previously considered for block fading channels from a channel estimation perspective under both TDM and superimposed trainings [9] [11], and from an information theoretic viewpoint [12] 13] For time varying channels, existing results tend to assume the RPP 1 scheme and optimize parameters such as pilot symbol spacing, power and rate allocations [1] 6] 7] In [6] for flat Rayleigh fading modeled by a Gauss Markov process ....

....to infinity, and with ergodic capacity as the metric in [14] All these pa pers showed that periodic placement in frequency is optimal. Placement issues for multiple antenna systems employing orthogonal space time codes with the CRLB for channel estima tion as the metric has been considered in [3]. The placement that minimizes the Cramer Rao Lower Bound (CRLB) for semi blind channel estimators was found in [4] It was shown here that QPP c placement is optimal under some constraints. It is quite surprising that the QPP c placement schemes turn out to be optimal for a variety of metrics. ....
