3GPP LTE is the advancement of the UMTS because of ever‐increasing requests for brilliant interactive media administrations as indicated by client's desires. Since downlink is dependably an essential factor in scope and limit viewpoints, extraordinary consideration has been given in choosing innovations for LTE downlink collector. In this paper, LTE-downlink receiver framework exhibitions of Channel Response estimations are tried and assessed utilizing FDD transmission plans. An insertion calculation is utilized to acquire all Channel Response estimations. In this model direct addition calculations utilized as a part of recurrence and image area. The high information rates and the high limit can be accomplished by utilizing the upsides of the two advances. These advances have been chosen for LTE downlink receiver. Pilot‐assisted channel estimation is a strategy in which known signs, called pilots, are transmitted alongside information to get channel learning for legitimate deciphering of got signals. This paper goes for channel estimation for LTE downlink receiver framework. The execution of the framework recreated in various remote channel models that comprises of AWGN, RAW AWGN and Veh A channels. The execution of the framework is assessed utilizing distinctive regulations, for example, QPSK, 16 QAM and 64 QAM. Execution of these calculations has been measured as far as Bit Error Rate (BER) Vs Eb/No.

In this contemporary world procuring our confidential data against some unknown person is very significant. Thus to have a high reliability of data security watermarking technique is applied before transmitting the data. This proposed work LCWT and DGT decomposition gives an effective technique to protect hypertensive related information based on reversible watermarking. LCWT has the superiority of multi-resolution fundamental analysis of wavelet transform and reflects representation of image domain in LCT. And using DGT decomposition the patient information has to embed inside high frequency subband wavelet and the watermarked information will be extracted by the receiver without any loss, to reconstruct the original image information. The reliability of the proposed method is analyzed by comparing the experimental results of similarity index, normalization and peak signal to noise ratio.
