Unit: ELEC5515: Gigabit Wireless Systems (6 CP)
Mode: Normal-Day
On Offer: Yes
Level: Postgraduate
Faculty/School: School of Electrical & Computer Engineering
Unit Coordinator/s: Professor Vucetic, Branka
Session options: Semester 2
Versions for this Unit:
Campus: Camperdown/Darlington
Pre-Requisites: None.
Brief Handbook Description: This unit of study aims to provide the theory and design aspects of high speed and short-range wireless systems operating in the unlicensed frequency bands. The targeted system is at multi-gigabits per second within a 100m operating space. Typical applications include wireless local (or personal) area networks.

At the completion of this unit, students will gain the essential knowledge to design a gigabit wireless system based any of the emerging standards.

The following specific topics are covered:

• international regulatory requirements on unlicensed frequency bands;

• the MAC and PHY overview of WirelessHD, ECMA and IEEE802.11/15 standards;

• an introduction of the industry design process and tools.

• 60 GHz transceiver architecture and high-speed ADC/DAC requirements;

• pre-amble and pilot signal design;

• initial acquisition techniques;

• OFDM techniques (automatic gain control (AGC); channel estimation; carrier and sampling frequency estimation and compensation; in-phase and quadrature (I/Q) imbalance characterization, estimation and compensation; soft-output algorithms; peak to average power ratio (PAPR) reduction and adaptive bit loading);

• bean-forming and multiple input and multiple output(MIMO) techniques;

• Case study: solutions for IEEE802.11 VHT
Assumed Knowledge: ELEC3305 AND ELEC3505. This unit assumes a competence in fundamental communications theory on modulation and equalization, digital signal processing techniques on filtering and FFT/IFFT, error-control coding and linear algebra.
