Performance of Space-Time Block Coding in Powerline and Satellite Communications
In this paper Space-Time Block Coding (STBC) is examined in powerline and satellite communications, comparing the gains that this coding-modulation technique provides to these communications systems. The powerline environment is assumed to be a frequency-selective, multipath fading environment with Additive White Class A Noise (AWCN), which is used to model the actual powerline noise characteri...
متن کاملSpace-time block coding for wireless communications: performance results
We document the performance of space–time block codes [13], [14], which provide a new paradigm for transmission over Rayleigh fading channels using multiple transmit antennas. Data is encoded using a space–time block code, and the encoded data is split into n streams which are simultaneously transmitted using n transmit antennas. The received signal at each receive antenna is a linear superposi...
متن کاملExtended balanced space-time block coding for wireless communications
Diversity techniques are very effective tools to increase signal reception quality in Rayleigh fading channels. A well-known method to increase diversity in multi-input multi-output (MIMO) communication is transmit antenna selection (TAS). However, TAS is very sensitive to feedback errors. One of the alternative techniques to TAS is balanced space-time block coding (BSTBC) which guarantees full...
متن کاملBroadband PowerLine Communications: Performance Analysis
Power line channel is proposed as an alternative for broadband data transmission especially in developing countries like Tanzania [1]. However the channel is affected by stochastic attenuation and deep notches which can lead to the limitation of channel capacity and achievable data rate. Various studies have characterized the channel without giving exactly the maximum performance and limitation...
متن کاملPerformance of Space-time Block Coding Using Estimated Channel Parameters
The paper presents a method of estimating channel parameters in wireless communications using space-time block coding (STBC). Moreover, in this paper, the concept of STBC is reviewed, the system model is described, the estimation method is derived, and the system performances have been simulated using MATLAB.
