Abstract

Using Tarokhs criteria for space-time codes [1] we analyze the design of the Linear Scalable Dispersion (LSD) codes [2]. These codes are designed to utilize large numbers of transmit antennas, to exploit high diversity factors and to trade spatial diversity gain for spatial multiplexing gain in a very flexible way. We investigate the diversity and coding gain for Rayleigh fading and show in particular that these codes are able to achieve full spatial and temporal diversity even in combination with spatial multiplexing.

Keywords
