Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - We have tried to describe two aspects of MIMO channels: channel capacity and channel modeling. We have analyzed the channel capacity of static and fading MIMO channels when the channel side information is available both at the transmitter and receiver, and when it is available only at the receiver. We have then modeled the MIMO channel in physical and angular domains to understand how it provides spatial multiplexing with the help of degrees of freedom. In physical domain modeling, we have modeled the MIMO channel in terms of individual physical paths. In angular domain modeling, we have described the MIMO channel with respect to fixed spatial basis functions defined by fixed angles that are determined by the spatial resolution of the antenna arrays. All the simulations have been performed on MATLAB 7.4.0.287 (R2007a).…

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - OFDM or Discrete Multi-tone with Cyclic Prefix is a multicarrier modulation scheme that provides high data rate transmission. It avoids both ISI and ICI by making use of a suitable cyclic extension of the transmitted data stream and allowing for a simple modulator structure. However, it leads to the loss of spectral efficiency. An alternative is OFDM based on OFDM/OQAM modulation that uses efficient pulse shaping instead of a guard interval, which leads to a gain in spectral efficiency. OFDMA base stations allow multiple users to transmit simultaneously on different subcarriers during the same symbol period. Various methods are used for assigning subcarriers and power to different users. The linear method used here, reduces the complexity of resource allocation. Here, to generate OFDM/OQAM symbol, Extended Gaussian function (EGF) and Square Root Raised Cosine (SRRC) pulse shapes are used. The frequency spectra are compared with rectangular pulse shape spectrum. Also in order to carry out the subcarrier allocation and power allocation in OFDMA, a low complexity algorithm is implemented.…
