Join us Friday at 12:00 for the weekly pizza talk. This week the pizza talk is in room PKI 377. The pizza talk is an informal event to showcase research being done around PKI.
This week's topic is:

In a SEMM system, multiple applications transmit their information simultaneously with different bit rates. The spreading method of each application is self-encoded spreading spectrum (SESS), where the spreading codes are derived from the previously transmitted bits rather than a pseudorandom code generator. Block chip interleaving is employed at the transmitter to combat deep fading over the channels. At the receiver, a decorrelation scheme separates the combined signals to reduce the crosstalk between different applications and provides a better estimation for the despreading sequence. Interference cancelation (IC) is also adopted to improve both the correlation detection and iterative detection (ID) performance.
