Implementation of WIMAX IEEE 802.16e Baseband Transceiver on Multi-Core Software Defined Radio Platform
Advancements in broadband and mobile communication have provided many privileges to its subscribers, such as high-speed data connectivity and good quality voice and video application services for economical rates. WIMAX is an eminent technology that provides broadband and IP connectivity to "Last mile" scenarios. It offers both line of sight and non-line of sight wireless communication. Orthogonal frequency division multiple access, which uses the concept of cyclic prefix to add additional bits at the transmitter end, is used by WIMAX on its physical layer. The signal is transmitted through the channel and then received at the receiver end. Afterwards, the receiver removes these additional bits in order to minimize the inter symbol interference, improve the bit error rate, and reduce the power spectrum.
