9. Implementation of 5.1Channel Decoder

The goal of the project is to design and build a system which converts stereo audio (2 channel) to surround sound (5.1). A “5.1” surround sound format means that there are five full-range speakers and one limited range speaker. This limited range speaker is used for bass frequencies, and is sometimes referred to as the Low Frequency Effects channel or “LFE.”

10. Implementation of DUC-DDC

DUC provides the link between the digital baseband and analog RF front end and is required at the transmitter of a generic transceiver. The sampling frequency of the baseband data stream is increased before it is modulated onto a high frequency carrier. The digital down converter (DDC) provides the link between the analog RF front end and the digital baseband of a receiver. The data is demodulated from the high frequency carrier and subsequently the sampling frequency of the data stream is reduced. The data stream is then compatible with the baseband.

11. VHDL Implementation of PTS algorithm for PAPR reduction in OFDM

Orthogonal frequency division multiplexing (OFDM) has become a popular modulation method in high-speed wireless communications. By partitioning a wideband fading channel into flat narrowband channels, OFDM is able to mitigate the detrimental effects of multi-path using a simple one-tap equalizer. However, in the time domain OFDM signals suffer from large envelope variations, which are often characterized by the peak-to-average power ratio (PAPR). High PAPR signals, like OFDM require that transmission amplifiers operate at very low power efficiencies to avoid clipping
