This paper provides a review on the IDMA (Interleave Division Multiple Access) technology in wireless communication system based on Interleaver. In this paper, IDMA technique is proposed in AWGN channel. IDMA is a multi-user scheme in which chip Interleavers are the only means of user separation. The receiver involves a chip-bychip iterative multi-user detection. The IDMA performance in terms of bit error rate, bandwidth efficiency and complexity reduction is discussed. However, we observe that during iterative process, the IDMA output performs well with ISI Cancellation when numbers of users increases. Indeed, the increase in the number of users requires the independent processing of MAI and ISI that is carried out in IDMA.

A new simple procedure was developed to simultaneously estimate metoprolol and atorvastatin and also validated by RP-HPLC method in tablet formulation. The separation mm, 5µm) column using the mixture of Phosphate buffer pH 3: Methanol 50:50v/v ratio as mobile phase. The injection flow rate was maintained at 1 ml/min, and run time was 10.0 mins. UV detection of both the drugs was achieved at 244nm at ambient temperature therefore can be employed to estimate metaprolol and Atorvastatin in other dosage forms as well.A new simple procedure was developed to simultaneously estimate metoprolol and atorvastatin and also validated HPLC method in tablet formulation. The separation of the peak was achieved on Inertsil ODS mm, 5µm) column using the mixture of Phosphate buffer pH 3: Methanol 50:50v/v ratio as mobile phase. The injection flow rate was maintained at 1 ml/min, and run time was 10.0 mins. UV detection of both the drugs was achieved at 244nm at ambient temperature. The results obtained for this method were in the acceptance criteria and therefore can be employed to estimate metaprolol and Atorvastatin in other dosage forms as well.A new simple procedure was developed to simultaneously estimate metoprolol and atorvastatin and also validated was achieved on Inertsil ODS-3 (4.6Ã-150 mm, 5µm) column using the mixture of Phosphate buffer pH 3: Methanol 50:50v/v ratio as mobile phase.

The chromatographic separation was clear at the flow rate of 1 ml/min, and analysis time of 10.0 min, UV detection was at 244 nm. The assay for metoprolol and Atorvastatin were found to be 100.03 and 99.82 respectively. The linearity results of the developed method was greater than 0.999. From the recovery studies, the method was found to be accurate as the % recovery of the drugs were within the acceptable range. From the forced degradation studies, the method was found to be stable as the results were NMT 15%. Therefore, from the results obtained, it can be concluded that this can be employed for estimation of Atorvastatin and metoprolol in other dosage forms.
