Symbol Error Rate Calculation for Alamouti Space Time Coded OFDM in Direct Conversion Receivers

Numerical Performance Evaluation of impaired OFDM Links using Alamouti Space Time Coding

“…Let |Ĥ 1,l | 2 = r 1 and |Ĥ 2,l | 2 = r 2 . It has been shown in [10] that the statistic of Z l is given by a two dimensional conditional Gaussian PDF what reads …”

“…In this paper, after introducing the general impaired OFDM system model (Sec.II) we give a detailed stochastic analysis of Alamouti STC OFDM received signals under the aggregate effect of channel estimation error and the already mentioned impairments in Sec.III. The aim is it to extend our findings of [10] on the numerical BER calculation for Alamouti STC OFDM systems under the aggregate effect of all the mentioned impairments. Based on [10], our intention is it to provide an easy-to-use closed form PDF of the received signals that finally allows Alamouti OFDM BER and capacity prediction without using costly and time consumptive simulation campaigns.…”
