Hi,
In LTE OFDMA is used in Downlink.OFDMA having High PAPR.signals with high PAPR requires highly linear power amplifiers inorder to avoid excessive intermodulation distortion so,amplifiers must be operate with a large backoff from its peak value.High PAPR is particularly critical for uplink...
Hi,
Try to read this book "c programming by yashwant kanetkar".once u complete reading this book then try to read "C programming by Dennis Ritchie".These two books almost covers all topics.
Hi,
FDMA is one among multiple access techniquies.dma(dynamic mem. access) is not at all related to this but,during code writing time allocation of memory normally use static memory allocation or dynamic memory allocation.donot compare FDMA with DMA.

MIMO is mainly to send more data at the same time over multiple tanmitters and receivers.
OFDM is mainly for multipath problem by splitting carriers into smaller subcarriers, and then broadcasting those simultaneously. This reduces multipath distortion and reduces RF interference allowing for...
Sobel is one among best filters to find out edges in image.By using this filter do it once in X-axis with main image and do it once inY-axis with main image.
