Baseband Receiver Design for Wireless MIMO-OFDM by Tzi-Dar Chiueh

By Tzi-Dar Chiueh

The moment variation of OFDM Baseband Receiver layout for Wirless Communications, this publication expands at the past variation with improved insurance of MIMO ideas, extra baseband algorithms, and extra IC layout examples. The authors conceal the total diversity of OFDM know-how, from theories and algorithms to architectures and circuits.

The ebook offers a concise but accomplished examine electronic verbal exchange basics earlier than explaining sign processing algorithms in receivers. The authors supply targeted remedy of matters - from structure to IC implementation.

  • Links OFDM and MIMO conception with implementation
  • Enables the reader to move conversation obtained options into undefined; layout instant receivers with appropriate implemntation loss; in achieving low-power designs
  • Covers the most recent criteria, resembling DVB-T2, WiMax, LTE and LTE-A
  • Includes extra baseband algorithms, like soft-decoding algorithms reminiscent of BCJR and SOVA
  • Expanded therapy of channel versions, detection algorithms and MIMO techniques
  • Features concrete layout examples of WiMAX structures and cognitive radio apllications
  • Companion web site with lecture slides for instructors

Based on fabrics built for a direction in electronic conversation IC layout, this ebook is perfect for graduate scholars and researchers in VLSI layout, instant communications, and communications sign processing. training engineers engaged on algorithms or for instant communications units also will locate this to be a key reference.

93 Gbps by wider bandwidth of 160 MHz, more compact constellation of 256QAM, and more spatial streams (up to eight layers). In addition, multi-user MIMO techniques are employed in the AP with eight antennas to allow simultaneous communications with up to four STAs, each equipped with two antennas [15]. 4/5 GHz bands. 16 GHz bandwidth. Owing to severe path loss, beamforming techniques must be adopted to suppress interference and to strengthen link quality in this standard [16]. 16 is the IEEE standard for wireless metropolitan area network (MAN), sometimes also dubbed WiMAX [17].

9(a). Independent data are modulated on different subchannels and then these subchannels are frequency-multiplexed. The purpose of the nonoverlap is to eliminate the possible interference among adjacent subchannels, also known as inter-carrier interference (ICI). Note that the guard band between two adjacent subchannels constitutes a waste of spectrum. 9(b), which saves up to 50% of the spectrum used. Toward this end, orthogonal frequency-division multiplexing (OFDM) was developed. 7 Pulse-shaping filters: (a) impulse response of the raised-cosine filter, (b) frequency response of the raised-cosine filter, (c) impulse response of the Gaussian filter, and (d) frequency response of the Gaussian filter.

1 depicts sample waveforms of binary ASK, binary FSK, and binary PSK. Note that ASK and PSK are linear modulations whose symbol waveforms are sinusoidal waveforms of the same frequency. A more compact and clearer representation of such a modulation is the phasor representations of all the possible symbols on a phasor plane. This representation is called the signal constellation of a digital modulation. 2(a) and (b). FSK, however, does not have a signal constellation, as its symbol waveforms use sinusoidal waves of different frequencies.
