This paper describes implementation of an offset quadrature phase shift keying (OQPSK)-pulse-shaping block as a part of digital transmitter. The implementation is based on 2.4 GHz-band IEEE 802.15.4 standard. In this paper, the implementation results are compared to the results of OQPSK modulator and pulse-shaping block in terms of simulation waveform, design size, and synthesis run time. These blocks were designed using Verilog code through Xilinx ISE as a new design method and been implemented on Spartan3E XC3S500E field programmable gate array (FPGA). Current review shows that configurations for the implementation of OQPSK-pulse-shaping block, require 26.4% slices, 22.9% sliced flip-flops, and 15.5% look-up tables (LUTs), which is much better than the results of OQPSK modulator and pulseshaping block. At clock frequencies of 2 MHz and 25 MHz, the synthesis run time for OQPSK-pulse-shaping block shows substantial improvement with 48 ns faster than the two blocks.

“…For Example, recently developed IC CC2420 from the Texas instruments can cover 20-30 m range at a power usage of 60-70mw [6][7][8]. However such power consumption and operational range are not a good choice for WBAN, where the transceiver design target is 1-5m operation range and also consumes low power [9][10].…”

“…The input data of convolution encoder block is in serial sequence with 1 bit word length. The (8,4) convolution encoder is adopted here as the Forward Error Correction (FEC), which has three parity check bits and one over all parity bit following every four information bits. For each consecutive 4 bits of input data, convolution encoder generated 8 bit code.…”

This paper proposes, convolution code for better performance of ultra low power transceiver comparing to Hamming code. It targets ultra low power consumption; with reliable Quality of Service (QoS). Low complex architecture is provided here with Application Specific Integrated Circuit (ASIC) which satisfies a good performance. Better packet synchronization and data recovery is helpful for the satisfactory functioning of the ultra low power transceiver. With a 1.1V supply and 4MHz system clock the base band transceiver can decrease the power up to 7mW.

This paper is aimed at the selection of encoding scheme for low power baseband transceiver IC for Wireless Body Area Network. In WBAN power consumption is necessary thing these days. To provide power consumption various designs are implemented . In this paper a low power baseband Transceiver IC is designed with different coding schemes like Hamming, BCH, LDPC codes and their power consumption are measured and compared. The results show that Low Density Parity Codes (LDPC) yields low power consumption among other coding schemes. The proposed method is simple and proves when applied for selection of effective power management coding scheme in Transceiver IC for WBAN. This coding scheme will be power efficient and also produces perfect error checking among other error checking codes taken in this paper.
