Analysis and comparison of the 4-PSK and 8-PSK STTC over Rayleigh fading Channels for determining Performance

Demands for capacity in wireless communications, driven by cellular mobile, Internet and multimedia services have been rapidly increasing worldwide. On the other hand, the available radio spectrum is limited and the communication capacity needs cannot be met without a significant increase in communication spectral efficiency. Coding techniques designed for multiple antenna transmission are call...

QPSK differential space time coding on different unitary matrices sets and initializations

This letter investigates a distinct set of complex unitary matrices for differential space time coding by using QPSK modulation. The numerical results show that the properly selection of the initial transmission matrix and the set of unitary matrices can efficiently improve the bit error rate (BER) performance, especially for the antennas correlated fading channel. The computer simulations are ...

Performance Analysis of Space Time Trellis Codes Over Nakagami Fading & Rayleigh Fading Channels: With Comparative Analysis

Space-time trellis codes provide both diversity gain and coding gain. There are two different design criteria proposed for spacetime trellis codes (STTCs), namely the rank and determinant criteria (RDC) and the Euclidean distance design criteria (EDC). In this paper, we present the performance of STTCs over Nakagami fading channels. Our results show that the STTCs designed for Rayleigh fading c...

Space-time signal design for time-correlated Rayleigh fading channels

The existing constructions of space-time codes or modulation have mainly focused on two ideal situations: either quasi-static or rapid fading channels. In this paper, we consider the design of robust space-time modulation for time-correlated Rayleigh fading channels. We show that the space-time signals of square size achieving full diversity in quasi-static fading channels can also achieve the ...

Performance of Space Time Trellis Code With Rayleigh Fading Scenario

Space Time Trellis codes provided maximum diversity advantage using simple decoding techniques. However, space-time block codes did not provide coding gain, and nonfullrate space-time block codes introduced bandwidth expansion. In this paper we implement space time trellis code using relay fading scenario. We present here the design of the 4psk with 2 transmit antennas and 1,2,4 receiver antenn...
