"Igniting broadband wireless access". That is the vision for WiMAX, which is
defined in the 802.16 standards to cover the frequency bands within the 2 to 66 GHz
region. It promises an OFDM air interface with data rates comparable to wireline
services (cable and xDSL). Coupled with QoS provisioning and support for NLOS
propagation, WiMAX offers the platform for real time multimedia communications in
addition to being able to replace the existing legacy PSTN. WiMAX also becomes the
perfect launch pad for service providers to roll out triple play. The standard based
products and availability of internet to anyone, anywhere and anytime will almost
guarantee the widespread adoption ofWiMAX everywhere.
This FYP attempts to simulate the working mechanism of a WiMAX receiver,
with focus on synchronization (inner receiver), via simulation in Simulink. The
undertaking will involve the baseband physical radio link. The proposed method of
synchronization is a novel hybrid of a modified version of the Schmidl and Cox
technique and the double sliding window packet detection. The inner receiver deals
with synchronization issues such as FFT timing offset and carrier frequency offset.
Offsets and impairments are deliberately introduced into the system to ensure that the
receiver is totally blind and to fully test the proposed algorithm.
Results indicate that the proposed method can harness the best features of both
worlds. Frame timing synchronization is achieved accurately without uncertainties of
detecting a plateau. On the other hand, frequency offsets are dealt with efficiently
using the tried and tested Schmidl and Cox technique. All in all, the proposed
synchronization scheme is very well suited for WiMAX systems. The proposed
method can achieve rapid synchronization with low overhead. |
