SufJicient conditions to ensure QAM space-time codes achieve full space diversity in quasi-static fading channel are presented. The conditions are on code words or generator matrices instead of on every code word pair. This simpl@es the check of full space diversity of a code. Based on these conditions, full space diversity parallel concatenated turbo codes are proposed to use in a multiple ele...

In this paper, we consider the issue of blind detection of Alamouti-type differential space-time (ST) modulation in static Rayleigh fading channels. We focus our attention on a π/2-shifted BPSK constellation, introducing a novel transformation to the received signal such that this binary ST modulation, which has a second-order transmit diversity, is equivalent to QPSK modulation with second-ord...

This paper proposes a class of full space diversity full rate space-time turbo codes. Both parallel concatenated and serially concatenated codes are designed. The full space diversity design is facilitated by a rank theory. Compared with space-time trellis codes, the simulations show the space-time turbo codes have excellent performance in both quasi-static fading channels and time varying fadi...

The problem of multichannel estimation for space-time coded transmissions over frequency-selective Rayleigh fading channels is addressed. Under fast fading conditions, receivers employing Kalman filtering and moderate complexity equalization schemes are proposed for both space-time block codes (STBCs) and space-time trellis codes (STTCs). Simulation results of the proposed receivers demonstrate...

The availability of multiple transmit antennas allows for two-dimensional channel codes that exploit the spatial transmit diversity. These codes were referred to as space–time codes by Tarokh et al. Most prior works on space–time code design have considered quasi-static fading channels. In this paper, we extend our earlier work on algebraic space–time coding to block-fading channels. First, we ...
