EC8652 WIRELESS COMMUNICATION
OBJECTIVES:
To study the characteristic of wireless channel To understand the design of a cellular system
To study the various digital signaling techniques and multipath mitigation techniques
To understand the concepts of multiple antenna techniques
UNIT I WIRELESS CHANNELS
Large scale path loss – Path loss models: Free Space and Two-Ray models -Link Budgetdesign – Small scale fading- Parameters of mobile multipath channels – Time dispersion
parameters-Coherence bandwidth – Doppler spread & Coherence time, fading due to
Multipath time delay spread – flat fading – frequency selective fading – Fading due to
Doppler spread – fast fading – slow fading.
UNIT II CELLULAR ARCHITECTURE
Multiple Access techniques – FDMA, TDMA, CDMA – Capacity calculations–Cellularconcept- Frequency reuse – channel assignment- hand off- interference & system capacitytrunking & grade of service – Coverage and capacity improvement.
UNIT III DIGITAL SIGNALING FOR FADING CHANNELS
Minimum Shift Keying, Gaussian Minimum Shift Keying, Error performance in fading
channels, OFDM principle – Cyclic prefix, Windowing, PAPR.
UNIT IV MULTIPATH MITIGATION TECHNIQUES
Equalisation – Adaptive equalization, Linear and Non-Linear equalization, Zero forcing andLMS Algorithms. Diversity – Micro and Macro diversity, Diversity combining techniques,
Error probability in fading channels with diversity reception, Rake receiver.
UNIT V MULTIPLE ANTENNA TECHNIQUES
MIMO systems – spatial multiplexing -System model -Pre-coding – Beam forming –transmitter diversity, receiver diversity- Channel state information-capacity in fading and
non-fading channels.
