Five Finger Rake Receiver Performance Analysis for Odd/Even Parity Maximal Spreading Code

The main complication in wireless systems is multipath fading. There is substantial damage in the mobile unit that receives signals due to multipath fading. The received signal deterioration is very high if the multipath path delay is lower than the chip duration. Rake receiver mitigates multipath fading phenomenon. Rake receiver combines different incoming signals by a large quantity of ‘sub receivers’ called as ‘fingers’. The multipath diversity principle is used in this receiver arrangement. Rake calculates the power from numerous transmitted signals. This paper presents the Bit error probability for Rake receiver using Odd parity or parity maximal codes for data spreading in the transmitter, considering mobile slow and flat fading channels. Performance Analysis of Rake receiver is publicized by applying MATLAB®.
