{"product_id":"9781608458295","title":"Block Transceivers: OFDM and Beyond","description":"\u003cp\u003eThe demand for data traffic over mobile communication networks has substantially increased during the last decade. As a result, these mobile broadband devices spend the available spectrum fiercely, requiring the search for new technologies. In transmissions where the channel presents a frequency selective behavior, multicarrier modulation (MCM) schemes have proven to be more efficient, in terms of spectral usage, than conventional modulations and spread spectrum techniques. The orthogonal frequency-division multiplexing (OFDM) and its related single-carrier (SC-FD) scheme are the most notorious MCM methods, since they not only increase spectral efficiency but also yield simple tranceivers. Both OFDM and SC-FD systems transmit redundancy in order to cope with the problem of intersylbol interference. This book presents OFDM-inspired systems that are able to, at most, halve the amount of redundancy used by OFDM systems while keeping the computational complexity comparable. Such systems, herein called memoryless linear time-invariant (LTI) tranceivers with reduced redundancy, require low complexity arithmetical operations and fast alogrithms. In addition, whenever the block transmitter and receiver have memory and\/or are linear time-varying (LTV), it is possible to reduce the redundancy in the transmission even further, as also discussed in this book. For the tranceivers with memory it is possible to eliminate the redundancy at the cost of making the channel equalization more difficult. Moreover, when time-varying block transceivers are also employed, then the amount of redudancy can be as low as a single symbol per block, regardless of the size of the channel memory. With the techniques presented in the book it is possible to address what lies beyond the use of OFDM-related solutions in broadband transmissions.\u003c\/p\u003e","brand":"Morgan \u0026 Claypool Publishers","offers":[{"title":"Default Title","offer_id":47056968777968,"sku":"9781608458295","price":40.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781608458295_p0.jpg?v=1763835501","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781608458295","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
