The results towards the end of June 2017, suggest that if an investor may have invested a sum of INR 1 lakh in the ARQ Midcap Stocks at the beginning of June 2016, his returns today would have surged by 42.66%, thereby enabling the investor a high profit margin. This first-of-its-kind, intelligent and predictive Wealth Management engine has already begun to change the industry dynamics by an excellent margin with its remarkable numbers standing as a testimony to the vision behind it.ĪRQ Midcap Stocks performance indicates the steady pace at which the investment engine is gaining momentum in the market. With an aim to build the company’s vision of ‘Digital Revolution’, almost two years ago, Angel Broking launched their champion product ‘ ARQ’, a data-backed machine intelligence mobile application that derived personalised recommendations for its users. ARQ Midcap Stocks outpaced the benchmark Nifty Midcap 100 by 8.87%, delivering 42.66% returns in the span of one year. 1307-1315, 1981.Angel Broking, India’s top retail focused investing firm’s hero product ARQ, has outperformed yet again despite the cautious nature of the stock market since the past year. ![]() Lin, “The Analysis of Some Selective Repeat ARQ Schemes with Finite Receiver Buffer”, IEEE Trans.

Under the AWGN channel, a throughputof 0.9 is achieved for any IPpacket size and at higher BER conditions compared to the Selective Repeat +Stutter Scheme 2 (SR + ST 2).An 8 dB improvement is achieved under the flat Rayleigh fading channel usingBCH(63, 51, 2) for a throughputof 0.9. The ARQ scheme gives optimum performance forM equal to 10fragments and fragment size of 75 bytes. Performance results are obtained with and withoutBose ChaudhuriHocquenghem (BCH) error correction codes under Additive White Gaussian Noise(AWGN) as wellas Flat Rayleigh Fading channels. Then,the performance of the proposed scheme is evaluated in terms of BER andIP packet size with theoptimum M and fragment size. ![]() The fragment size is alsocalculated for actual datathroughput for a given IP packet size, both with and without Forward ErrorCorrection (FEC). Optimum values for both parameters arecalculated for Bit ErrorRate (BER), throughput, IP packet size, and delay. After the IPfragments are received without error, the system returns to the SR mode.The optimization of the ARQ is done in terms of two parameters: fragment sizeand the optimum number of packetsto be transmitted in the MC mode, M. In the MC mode, multiple copies of the erroneous fragment aretransmitted. If a fragment is negatively acknowledged after the last fragmentis transmitted, then the system goes into theMC mode. The ARQ scheme works in the SR mode until the last IPpacket fragment istransmitted. This paper presents, optimizes, and analyzes the performance of a novel hybridSelective Repeat/Multi Copy(SR/MC) Automatic Repeat Request (ARQ) scheme for transmitting fragmentedInternetProtocol (IP) packets.
