Condizione: 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.…
